Outbound WxC with LGW calls fail but UCM over the same LGW work

[dominic.fidler]

possibly a unique position here. but:

I had UCM (dedicated instance) with local gateway in Australia.  this has been working well for some time.

I am migrating users to Webex Calling, utilising the same gateway.  I am using the same outbound dial-peer and voice translation-rules etc.., number are formatted correctly etc.

I am finding that local, outbound calls from WxC registered devices fail, yet the calls made from a UCM-registered device works.  to the exact same numbers.

To make it even more confusing, when I dial an international number, both devices successfully make the call.

Has anyone else had a similar experience?

Assuming that you have debug output from the LGW for both working and non-working calls and again making the assumption that the debugs that you have are for debug ccsip messages and debug voip ccapi inout. If this is so are you in a position so that you can share this with the community? If you do please collect the output and put it into a text file that you attach to the response.

I have a scenario in our environment where I place a call from an on prem registered phone to a WxC number and I get 2 way audio and 1 way video.  I can duplicate the problem condition on demand, and particularly I will share some LGW logs of a problem call.  In this calling scenario I'm calling from on prem phone with ext. 1237161, calling to WxC phone ext. 1237381.  Here is the unique rub.  If I answer the call on my WxC 8875 phone all is well with 2 way audio and video, however, if I answer the call on my DeskPro, I will have 2 way audio and 1 way video (no video at the side of on prem phone).  See the attached LGW logs of these 2 calling scenarios.  

Edit after I had some confusion on the logs and calling scenarios.  All correct now.

LGW Logs Call 1 is calling from the on prem 8865, answering from the WxC 8875. (2 way audio / video)
LGW Logs Call 3 is calling from the on prem 8865, answering from the Deskpro (2 way audio / 1 way video )

IMHO your question isn't matching the question/topic of the OP. With that it is advised for you to create your own post to ask your question.

My apologies, I thought the topics similar given that the calls are between on prem and WxC, further with LGW involved.  I'll move this to another thread.
