[cisco-voip] transfer to SIP endpoint (Nuance Speech Attendant) no longer working after upgrade from v7.1(5)SU3 to v9.1(2)SU1

[Lelio Fulgenzi]

Thanks Brian. 

I did engage the TAC and they were able to track it down to Nuance sending back an "inactive media" parameter setting. Nuance has confirmed that they've seen something like this before and are working at possibly recreating a patch they did for a previous version. 

The TAC did mention something about the order preference of MR(G)L being done differently though.

Lelio, 


That bug was fixed in 9.1.2 so you should have the fix as well. We'll probably need to take a look st the SIP messaging either from a packet capture or CallManager traces ideally to see what is going on with these calls.

ok, transfers to Cisco SIP devices work fine. 

found this bug after looking at list archives... 

https://tools.cisco.com/bugsearch/bug/CSCug50634 


one-way voice with diverted 3rd party phones, from sip via mgcp/qsig 

not sure if it's related....

OK, this is a weird one. It took a while to isolate, but it seems like calls that are transferred to SIP endpoints are not working after an upgrade from v7.1(5)SU3 to v9.1(2)SU1. 

We don't have many SIP endpoints, in fact, we only have 3, but two of those are our Nuance Speech Attendants. The other is an ATA-187. 

We're going to bring our spare ATA-187 up for additional testing to see if it's one way audio, or no audio, etc. But that may take a while since we're not too used to bringing these up quickly. 

I'm also going to consider opening a TAC case, cause I have no idea where to look for something like this. Not being familiar with SIP endpoints too much. And never seeing something break after a transfer. :( 

Any ideas anyone? 

Lelio
