Small business E911 solution
We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn't require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).

I'm very curious if you find something. I'm not aware of anything cost effective at your size. RedSky's minimum purchase for a CUCM based system is 12-14k.

Have you looked at moving to a hosted phone system? Almost every vendor I'm aware of includes E911 therein

No, hosted solution isn’t an option as we have a number of custom solutions like ring downs, etc…

We already have CUCM and Expressway working fine, I just need directions on the simplest solution for E911 for MRA workers.

Re: [External] Re: Small business E911 solution [ In reply to ]
We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

CUCM/CER is not complaint with Ray Baum’s act Phase II. You will need to deploy Intrado or Redsky to be compliant. I’ve only looked at them for existing CER customers, but I believe at least redsky has an option without CER. Don’t worry you have less than a month until Phase II goes into effect on January 6th 2022.

Re: [External] Re: Small business E911 solution [ In reply to ]
If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

Best,

Adam

Re: [External] Re: Small business E911 solution [ In reply to ]
Intrado is the only one that I know of that has the ability to deal with just about every single solution. The only one they can’t handle yet is the softphone within citrix which nobody else I know can deal with. That solution comes in a few months.

The ERS service from Intrado is the cheaper of the two solutions. There really isn’t anyway to accomplish what you want without $$$$. The risk you have is that if it doesn’t route or is mis-routed you could possibly then have legal issues.

The biggest issues we had was softphones in virtual environment(citrix), non-did extensions, users that move around and need to dynamically change location on the fly etc.

Most of the vendors like redsky are just the front end as it seems like Intrado literally has a monopoly on the backend E911 service.

If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

Subject: [cisco-voip] Small business E911 solution

[EXTERNAL]

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).

Re: Small business E911 solution [ In reply to ]
9Line 911 is the cheapest option out there and does dynamic location
updates for users on Jabber or desk phones including MRA desk phones.

They do rely on CER though and the user is prompted to update their
location via the CER portal. If you're on Flex licensing, CER is
free/included.

This may get confusing though on the Shared DID. You can use cheap DIDs
just for E911 purposes I believe.

You're probably too small for UCM Cloud or Webex Calling Dedicated Instance
which include Redsky E911 for free now as well. Webex Calling also
includes Redsky E911 now but you'd have to change your backend to no longer
be CUCM-based.

Re: [External] Re: Small business E911 solution [ In reply to ]
We are going down the same road to find a solution to fit our environment, which seems similar to the original post. We have physical phones in the office, sometimes in multiple offices with same DN and a home phone using MRA with the same DN. Some Jabber softphone usage mixed in there as well in a VMware VDI environment.

Redsky want’s a separate ELIN for each MRA phone and Intrado says they can use CER or their gateway to track the MRA phones. The VDI support is something they say they are working on, but no support at this time.

Sounds like we need to stand up CER at least with Intrado or plan to burn quite a few DID’s for ELIN use.

I do wish there was a better solution, but I have not come across one yet. I will keep an eye on this thread.

Subject: [cisco-voip] Small business E911 solution

[EXTERNAL]

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).

Mobile access aside, how are you going to handle physical infrastructure? Right now, our switches have been deployed using “shortest path” methodology. This means, one switch stack could service one quadrant of a building and three separate floors. It would take years to document the ports. And they’d be out of date before you pushed the save button. Let’s not forget people can attach a 100ft patch cord and wire the other side of the building that the port doc says it services.

I guess we could start with building based location, which is better than nothing.

We are going down the same road to find a solution to fit our environment, which seems similar to the original post. We have physical phones in the office, sometimes in multiple offices with same DN and a home phone using MRA with the same DN. Some Jabber softphone usage mixed in there as well in a VMware VDI environment.

Redsky want’s a separate ELIN for each MRA phone and Intrado says they can use CER or their gateway to track the MRA phones. The VDI support is something they say they are working on, but no support at this time.

Sounds like we need to stand up CER at least with Intrado or plan to burn quite a few DID’s for ELIN use.

I do wish there was a better solution, but I have not come across one yet. I will keep an eye on this thread.

Intrado is the only one that I know of that has the ability to deal with just about every single solution. The only one they can’t handle yet is the softphone within citrix which nobody else I know can deal with. That solution comes in a few months.

The ERS service from Intrado is the cheaper of the two solutions. There really isn’t anyway to accomplish what you want without $$$$. The risk you have is that if it doesn’t route or is mis-routed you could possibly then have legal issues.

The biggest issues we had was softphones in virtual environment(citrix), non-did extensions, users that move around and need to dynamically change location on the fly etc.

Most of the vendors like redsky are just the front end as it seems like Intrado literally has a monopoly on the backend E911 service.

Subject: Re: [cisco-voip] [External] Re: Small business E911 solution

If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

Best,

Adam

We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

Maybe Intrado? Not sure their minimum requirements but I know we started with them when they were West, with only a couple hundred DIDs.

I’m very curious if you find something. I’m not aware of anything cost effective at your size. RedSky’s minimum purchase for a CUCM based system is 12-14k.

Have you looked at moving to a hosted phone system? Almost every vendor I’m aware of includes E911 therein

Ah the Russian university method of networking

Building is better than nothing though – and at least with phones you know what’s on the other end of the cabling. You could prompt the customer at their device to let you know where they are. Other than more extreme measures that’s probably a good start to a doc audit. If they run a patch cable to another room/floor/planet from the same switch port … not much to do other than get out the scissors.

The ERS service from Intrado is the cheaper of the two solutions. There really isn’t anyway to accomplish what you want without $$$$. The risk you have is that if it doesn’t route or is mis-routed you could possibly then have legal issues.

The biggest issues we had was softphones in virtual environment(citrix), non-did extensions, users that move around and need to dynamically change location on the fly etc.

Most of the vendors like redsky are just the front end as it seems like Intrado literally has a monopoly on the backend E911 service.

If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

Best,

Adam

We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

I’m very curious if you find something. I’m not aware of anything cost effective at your size. RedSky’s minimum purchase for a CUCM based system is 12-14k.

Have you looked at moving to a hosted phone system? Almost every vendor I’m aware of includes E911 therein

Subject: [cisco-voip] Small business E911 solution

[EXTERNAL]

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).

We have each floor or each single floor location on separate voice subnet and plan to assign a separate ELIN to each floor/location. We are small enough that this is currently manageable, but would be much more difficult for a large campus environment.

Mobile access aside, how are you going to handle physical infrastructure? Right now, our switches have been deployed using “shortest path” methodology. This means, one switch stack could service one quadrant of a building and three separate floors. It would take years to document the ports. And they’d be out of date before you pushed the save button. Let’s not forget people can attach a 100ft patch cord and wire the other side of the building that the port doc says it services.

I guess we could start with building based location, which is better than nothing.

We are going down the same road to find a solution to fit our environment, which seems similar to the original post. We have physical phones in the office, sometimes in multiple offices with same DN and a home phone using MRA with the same DN. Some Jabber softphone usage mixed in there as well in a VMware VDI environment.

Redsky want’s a separate ELIN for each MRA phone and Intrado says they can use CER or their gateway to track the MRA phones. The VDI support is something they say they are working on, but no support at this time.

Sounds like we need to stand up CER at least with Intrado or plan to burn quite a few DID’s for ELIN use.

I do wish there was a better solution, but I have not come across one yet. I will keep an eye on this thread.

Intrado is the only one that I know of that has the ability to deal with just about every single solution. The only one they can’t handle yet is the softphone within citrix which nobody else I know can deal with. That solution comes in a few months.

The ERS service from Intrado is the cheaper of the two solutions. There really isn’t anyway to accomplish what you want without $$$$. The risk you have is that if it doesn’t route or is mis-routed you could possibly then have legal issues.

The biggest issues we had was softphones in virtual environment(citrix), non-did extensions, users that move around and need to dynamically change location on the fly etc.

Most of the vendors like redsky are just the front end as it seems like Intrado literally has a monopoly on the backend E911 service.

If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

Best,

Adam

We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

Subject: [cisco-voip] Small business E911 solution

[EXTERNAL]

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).

I heard about this thread and wanted to chime in, in case someone else comes along with a similar use case.

Consider the following:

1. A small environment with all physical phones
2. On-prem & remote phones do NOT move
3. The # of locations is very manageable

This is a perfect use case for the free Native Emergency Calling feature. Map each location to a device pool, assign an ELIN, set the address w/your carrier for the ELIN, and you’re done.

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home.

9Line 911 is the cheapest option out there and does dynamic location updates for users on Jabber or desk phones including MRA desk phones.

They do rely on CER though and the user is prompted to update their location via the CER portal. If you're on Flex licensing, CER is free/included.

This may get confusing though on the Shared DID. You can use cheap DIDs just for E911 purposes I believe.

You're probably too small for UCM Cloud or Webex Calling Dedicated Instance which include Redsky E911 for free now as well. Webex Calling also includes Redsky E911 now but you'd have to change your backend to no longer be CUCM-based.

I want to thank Mark & 9line911 for taking the time to step me through these options especially since the end result is that for our small environment, we won’t need a third-party solution such as 9Line911.

I heard about this thread and wanted to chime in, in case someone else comes along with a similar use case.

Consider the following:

1. A small environment with all physical phones

2. On-prem & remote phones do NOT move

3. The # of locations is very manageable

This is a perfect use case for the free Native Emergency Calling feature. Map each location to a device pool, assign an ELIN, set the address w/your carrier for the ELIN, and you’re done.

Intrado is the only one that I know of that has the ability to deal with just about every single solution. The only one they can’t handle yet is the softphone within citrix which nobody else I know can deal with. That solution comes in a few months.

The ERS service from Intrado is the cheaper of the two solutions. There really isn’t anyway to accomplish what you want without $$$$. The risk you have is that if it doesn’t route or is mis-routed you could possibly then have legal issues.

The biggest issues we had was softphones in virtual environment(citrix), non-did extensions, users that move around and need to dynamically change location on the fly etc.

Most of the vendors like redsky are just the front end as it seems like Intrado literally has a monopoly on the backend E911 service.

Subject: Re: [cisco-voip] [External] Re: Small business E911 solution

If the devices are “remote” then I believe it is limited to the unique DID formed between the extension on the device and the e164mask with CER. V911 solutions all seem to use call routing and can’t differentiate which thing originated the call in any way other than the calling number. That’s where I am stuck being MRA only with Jabber. We’re also looking at 9Line, as they offer V911 and a UCM-direct approach for locations, but I believe in both cases it will still require some sort of unique DN, it just offers perhaps a better experience than the off-premise portal in CER for the customer to update their location as appropriate.

Best,

Adam

We have a SIP provider. The issue is that the user requires the same Prime DN no matter their location. We have a user, for example, at our NY office, he has a two different home offices in Massachusetts and one in Idaho. Our SIP provider in order to route E911 requires each phone to an unique DID, which our users will not accept.

What is the easiest solution with on-premise CUCM that allows me to satisfy E911 regulations, especially the ones that go into effect in January, without having to have everyone have an unique prime-dn at each location. Is Cisco Emergency Responder the only choice?

Subject: RE: Small business E911 solution

I’m very curious if you find something. I’m not aware of anything cost effective at your size. RedSky’s minimum purchase for a CUCM based system is 12-14k.

Have you looked at moving to a hosted phone system? Almost every vendor I’m aware of includes E911 therein

Subject: [cisco-voip] Small business E911 solution

[EXTERNAL]

We are in the process of moving from legacy ISDN PRI for inbound/outbound dialing to SIP, and E911 has hit us in the face. We have less than 50 users, where > 90% currently are working from home. They have the same prime dn for both the office phone and their home phone. We have users that have phones in 3-4 locations including in multiple states. What is the simplest solution to setup and maintain that doesn’t require a user to have a separate DID in each location? Cisco Emergency Responder looks like major overkill.

Our environment is:
CUCM 14.x
Cisco Expressway 14.x for MRA
Cisco 8861 SIP phones (both at home and at work).
