             Summary: PJSIP picks wrong media IP address for listening RTP
                 Key: ASTERISK-28993
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28993
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip, Channels/chan_rtp
    Affects Versions: 16.11.0
         Environment: Debian GNU/Linux 9
            Reporter: Marin Odrljin


We are having multiple local IP addresses 10.5.20.42 ,.52, ,.62, ,.72 for multiple PJSIP trunks toward 2 different provider IP addresses. SIP INVITE sends SDP as following:
{code}
c=IN IP4 10.5.20.42
m=audio 12442 RTP/AVP 8 3 101
{code}
but UDP listening address is the last one .72:
{code}
ss -na
udp    UNCONN     0      0      10.5.20.72:12442                 *:*
{code}
So the result is no incoming RTP packets are comming into Asterisk - no IN audio.

Intersting thing is that in Asterisk 13 we have had the same configuration and it worked because Asterisk was listening on all IPs 0.0.0.0
