Hello All , I configured for SIP TLS + SRTP and i was trying to make calls between 2 registered softphones. One phone is a bria android softphone and it is push registered from the bria's push server (FSTest2 -4002) . The other phone is a softphone running on windows desktop (FSTest1 - 4001) . In this scenario it was noticed that the call from 4001 to 4002 is failing because , the call invite being sent to the push server does not have SRTP in it.. So it return unsupported media and is failing. Following are the log files for this scenario. https://pastebin.com/J2PkFVJa If i keep the phone 4002 in the foreground of the mobile and hence it is directly registered with freeswitch instead of a push registerd , it is noticed that the call is working fine and the call from 4001 to 4002 will ring the bria softphone 4002 because In this case the call INVITE being sent from the SIP server/PBX to the bria softphone contains SRTP, Following are the logs for this scenario. https://pastebin.com/1849GVQk Our freeswitch version is 1.10.7-release+git~20211024T163933Z~883d2cb662~64bit . I am trying to find a solution to this issue for last 2 days without any luck. Any help is highly appreciated. Thanks and Regards Abdul Rasheed
