We are observing that scheduled conference call from TMS connects fine but fails to call one of the participant which is C60 codec. The TMS Trap logs for this particular endpoint shows "Scheduling Error" with details as call failed. It shows that MCU tried connecting to endpoint. If I see call log it shows incoming call coming to C60 but lasted for 13 secs and got failed with Cause Code as 16 (which I think means normal call clearing). Please find the details of call log below:

Please help me in finding the possible cause of this. We tried calling back to the conference number and got connected. Issue happens when TMS tries to dial the call. TMS is located in US and MCU used for the conference was also in US. The c60 which was unable to join is in India. Rest all the endpoints located in India were able to join the conference without any issue.
Thanks in advance!
