i have TC5 endpiont registered to VCS 7.1 and there is tls SIP trunk between VCS and CUCM and another one between CUCM and CTMS.
the call flow is as follow:
TC5-->VCS 7.1-->CUCM 8.6-->CTMS 1.8
my question is should the encryption work for TC5 attending meeting hosted on the CTMS 1.8? is it supported ?
when there are only cts endponts in the meeting, encryption works fine. only when TC5 joins, encryption breaks
