Hello -
I am trying to decide if I have stumbled across a bug in PJSIP or I am just
missing something. My Asterisk has two interfaces, an "internal" eth0
and
an "external" eth1. In pjsip.conf, I define the following transports:
[trusted]
type=transport
protocol=udp
bind=10.xx.yy.zz:5060
[untrusted]
type=transport
protocol=udp
bind=12.4.aa.bb:5060
My internal endpoints use transport=internal and external endpoints use
transport=external. I guess that's obvious.
My netstat shows both transports listening:
Proto Recv-Q Send-Q Local Address Foreign Address State
PID/Program name
udp 0 0 12.4.aa.bb:5060 0.0.0.0:*
25494/asterisk
udp 0 0 10.xx.yy.xx:5060 0.0.0.0:*
25494/asterisk
Everything works fine, most of the time. INVITEs, 1XX, 2XX are sent to the
right interface using the right source IP. But, when Asterisk tries to send
a BYE to any internal endpoint, it sends using the external IP, but it is
sent of the correct internal interface eth0. Only the IP layer is
incorrect. The SIP layer has the correct IP in the Via header. From what I
can tell, only BYE is affected.
I didn't have this problem with chan_sip. Am I just missing some
configuration?
To test, I have set up the most simple extension I can think of, and it
duplicates the condition:
exten => _9090,1,Answer
same => n,Wait(2)
same => n,Hangup

I assume that the problem was resolved between the two releases. -------------- next part -------------- An HTML attachment was scrubbed...
