voice-classs sip audio forced is cleaner, but as you said that needs a code
upgrade.  I would rock this until then.

Subject: [cisco-voip] Specific Off-net Called Numbers Being Dropped When
Called From Jabber

 

Hi folks, we're using CUCM 12.5.1.14900-63, and CUBE on a pair of 2921
routers running IOS 15.5(3)M2. We've been using this configuration to route
inbound and outbound PSTN calls via our TSP in the UK, Gamma, for a few
years now with no major problems.

 

Recently, however, we changed our travel booking agent to a new company
called Clarity BT and have found that none of our Cisco Jabber softphone
users can call their number, 03330100045, which appears to be hosted with a
company called Redcentric. Calls from any of our Cisco deskphones, and a
small volume of users we have on MS Teams Voice, who also route out via
Gamma using Direct Routing, can connect with no problems, as do calls from
our mobiles.

 

The calls from Jabber fail within a second or two of being placed, with no
message or tone. Looking at the SIP traces, they're rejected with "403
Forbidden"/" Reason: Q.850;cause=57", the CDR records this as a destCause of
57,  "Bearer capability not authorized"

 

I've raised a support case with Gamma and they're focussing on the fact that
calls from Jabber clients appear to be including SDP video information in
the call setup and have asked me if it's possible to stop Jabber sending
this. I've set my Jabber client to not "Always start my calls with video",
but this didn't change anything, and it's notable that I'm successfully
placing calls to the problem number from a Cisco 8865 handset that is also
video enabled and sends similar video SDP information.

 

It's worth mentioning that the SIP sessions are all sending the bare minimum
of g711ulaw, g711alaw and g729 annex b along with whatever else the device
is capable of, so it's not like it's failing to negotiate and audio codec.

 

So, has anyone had similar experience and know a solution? I tried looking
for ways to filter out the SDP video stuff at the CUBE, but my Google-fu
failed me (although I think this is a red herring due to the 8865 always
connecting.

 

Below is a capture of a failed call from a Jabber client to the problem
number with the IP addresses obfuscated:
