Morning folks .. curious as to what, if anything, folks are doing with MS teams direct routing via CUBE and hunt groups in CUCM? We have a client that’s looking to throw out jabber/Webex for softphone but keep CUCM hardphones. They have a quite a few hunts and would like to keep the CUCM hunt functionality intact while routing the line group DN’s to  MS Teams via SNR. My particular issue is this:

 

What I’m seeing is that CUCM sends the initial invite, to the DNs of the users in a line group, to CUBE with the calling party name of the user being called and no info/indication that it’s a hunt. For instance, if you’re in a line group that rings in jabber, you see that the call is for that hunt group. In my scenario, in Teams, Teams only shows that the incoming call is to the user originally being called and not from the hunt.

 

So flow is like this … user Albert Einstein calls William Shakespeare, William Shakespeare’s devices ring, then covers to a broadcast hunt. Users Nikoal Tesla and Alexander Graham Bell are in that hunt group and in Webex and jabber we see the call is for the hunt group.. On Tesla and Bell’s MS Teams client, they see the incoming call from Albert Einstein not that its from his hunt coverage.

 

Snippet of original invite from CUCM to CUBE (albert Einstein being the original caller and the FROM: sip:+16462931240@10.104.253.47      being the 4 digit to e164 translation to route into MS Teams via SNR):

It has been a minute, but I believe the RDP does not carry device specific headers that would indicate hunt group info (if that’s how that is done) , but I couldn’t find anything else on how that worked when prowling around.

You do get these though:

Diversion: sip:1248@10.100.101.41;reason=follow-me;privacy=off;screen=yes
Diversion: "William Shakespeare" sip:1248@10.100.101.41;reason=unconditional;privacy=off;screen=yes

But that comes from the original CFNA to hunt pilot, so that probably doesn’t help with what you’re doing.

What sort of header support does Teams have for diversion headers? Does it at least display “For William Shakespeare” or something ?
