Scott:
I setup an Cisco 837 Router (built-in ADSL modem) that VPNs back to our
corporate office. The remote user has a 7940 IP phone and the QOS I
used was pretty basic by giving VoIP traffic precedence over data
traffic.

Personally, setting up and 837 router is a lot more work than setting up
a PIX 501 or 506E for this application.

Subject: [cisco-voip] Voice over ADSL PPPoATM

Is anyone currently using IPT over an ADSL connection using PPPoA.

Looks something like this:

Home - cisco 675 ----- ADSL ------- Telco ATM ---------- Work - router -
LAN -CM 3.3.4 - VGW -PSTN.

Anything to note? QoS? Any comments or Suggestions?

TIA

Scott

We did this exact scenario and had to fall back to a T1. PPPoA vs. PPPoE
was a non-issue. Lack of QoS in the Telco ATM network was a
show-stopper. Needless to say the telco had no interest in making it
work. There are some sticky NAT traversal issues with phones and
CallManager. There are some third parties solutions popping up to
address this. We set up GRE tunnels to our CM to work around them.

I have several sites that use a PIX 501 to do a VPN back to the head
office, Since the PIX doesn't really support QOS I just changed my
codec to G729 for those calls. We aren't using PPPOA but are using
Cable modem (docsis) and so far we haven't had any problems...

There is an existing Cisco solution to NAT traversal, which is
to enable the SCCP application layer gateway in the IOS router
or the PIX. IOS calls this 'cbac', PIX calls this 'fixup'. As
you stated, I understand at least one 3rd party is working on
nearly-identical functionality as well.

In any case, if you don't trust the underlying network (such
as the Internet), your VoIP traffic from a branch office
to corporate office should be protected by an IPsec tunnel.
