Using Asteirsk 13.28.1:
If I configure my pjsip transport to handle NAT from the Internet:
external_media_address=[external address redacted]
external_signaling_address=[external address redacted]
When a call comes from a TCP registered SIP client on the Internet,
Asterisk is setting the IPv4 address in the "o=" and "c=" lines of the
SDP ICE payload to "(null)":
o=- 3654 548 IN IP4 (null)
c=IN IP4 (null)
IPv4 addresses in all of the a= lines are still correct.
This "(null)" of course causes the caller to fail to complete the call.
Is there something more I have to do to have Asterisk/pjsip properly
set the IPv4 address in the SDP ICE payloads?
