Hi guys! I have configured my FS server to support TLS/SRTP... but I am facing the problem of providing the service only to selected destinations. Calls fails when calling to endpoints with no tls/srtp, for example a ext registered in the UDP port. Also fails when an outgoing call is routed to an external provider with no support. Using tls ONLY works just fine if connecting to external or udp only endpoints, it seems like FS is taking care of signalling from endpoint to the server and from there is goes as needed to the b-legs. When using SRTP however it fails. Can I configure FS to support TLS/SRTP to the server and from there using it as needed? For example: A_LEG: TLS/SRTP - > B_LEG: EXT with UDP only A_LEG: TLS/SRTP -> B_LEG: EXT with TLS/SRTP A_LEG: TLS/SRTP -> B_LEG: external channel, provider with no TLS/SRTP Thanks in advance with any help. -- Víctor E.
