Rusty Newton commented on ASTERISK-22717:
-----------------------------------------

I noticed you don't have a TLS transport configured. That shouldn't be required for SRTP configuration in Asterisk (Though SRTP is less secure without TLS from my understanding) Out of curiosity, is the behavior any different, when you setup and use a TLS transport for that peer?
