[cisco-voip] CCM<->CUBE<->MS Teams via Direct Routing

Hi Jinto,

Got it in the end. Forcing the CODEC to G711ulaw got the call to go a little further and log this:

2021-04-19 16:38:59 local3/7  REASON: Q.850;cause=79;text="dc5cd339-27a3-4bbd-acee-af97493d3c39;InternalDiagCode: MultiplexingMediaSsrcRangeMissing, InternalErrorPhrase: Multiplexed media description does not specify an SSRC range (x-ssrc-range or x-multi-stream)"

I was modifying the attributes for media bypass disabled, when it was enabled. I just removed the modifications.

Thanks for your help,
Hefin

Hi Hefin,


Please check if you have an allow-connections sip to sip under the "voice service voip" configuration. Also, try to force early offer by adding "early-offer forced"



Thanks!

Jinto.

Hi Jinto,



Forcing the CODEC still didn't work :

ZZZZZZ#show dialplan number +441970YYYYYY | incl codec

        codec = g711ulaw,   payload size =  160 bytes,

        video codec = disable

        voice class codec = `'

        codec = g711ulaw,   payload size =  160 bytes,

        video codec = disable

        voice class codec = `'



I still think it's a CODEC issue somewhere, but I can't see where from at the moment.



Thanks,

Hefin

Hi Jinto,



Hmm, not the correct Codec being set. I'll hard code the CODEC now and see what happens.



ZZZZZZZZZ -gw#show dialplan number +441970XXXXXX | incl codec

       voice-class codec = 1

        codec = g729r8,   payload size =  20 bytes,

        video codec = disable

        voice class codec = 1

        voice-class codec = 1

        codec = g729r8,   payload size =  20 bytes,

        video codec = disable

        voice class codec = 1



Thanks,

Hefin

Hi Hefin,



Can you run a sh dialplan number and make sure that it's hitting the correct outgoing dial-peer from CUBE, also instead of using voice-class codec 1 try to hard code the codec in the outgoing dial-peer



Thanks!

Jinto.

Hi Everyone,



I've it a snag with a setup, and I can't see what it's failing on.

Calls from MS Teams<->CUBE<->CCM route and work correctly, but not the other way.



I just get a "SIP/2.0 488 Not Acceptable Here" which is usually CODEC, but I'm forcing the CODEC to G711ulaw as described in 'Direct Routing for Microsoft Phone System with Cisco Unified Border Element (CUBE)'
