Matt Jordan commented on ASTERISK-20838:
----------------------------------------

Can you also provide your sip.conf, as well as a pcap of the SIP message traffic?

Somehow the SRTP structure is non-NULL on the SIP channel when it appears as if no SRTP session was initiated. I'm curious if your SIP peer negotiated SRTP at all, or if it somehow is not being set to NULL at some point in the lifetime of the channel.
