Hi all,<br>
I have an issue with asterisk 13 and pjsip. I guess it is somehow
Firewall related, but I'm unsure.<br>
<br>
A registration to Sipgate is established successfully:<br>
<br>
<br>
<font face="Courier New, Courier, monospace"><Registration/ServerURI..............................>
<Auth..........> <Status.......><br>
==========================================================================================<br>
<br>
pjsip_sipgate/sip:sipgate.de:5060
pjsip_sipgate Registered </font><br>
<br>
<br>
Calling the registered number is even successfully shown in asterisk
(it is a freepbx installation).<br>
But when doing a second call the number is busy ("provider" busy, I
don't see anything in asterisk verbose mode).<br>
Sending a pjsip unregister results in the following messages:<br>
<br>
<font face="Courier New, Courier, monospace">[2016-10-15 10:03:22]
WARNING[10162]: res_pjsip_outbound_registration.c:761

Reachable. RTT: 434.393 msec<br>
== Endpoint pjsip_sipgate is now Reachable<br>
</font><br>
so it is somewhat clear, why i get a busy, because the endpoint is
not reachable. But WHY is the endpoint not reachable?<br>
<br>
Regarding the architecture: I have two routers cascaded, that is
unfortunately necessary. On the first router (vDSL-access router) I
have forwarded nearly everything to the second router (Bintec rj
353), where a port forwarding for relevant ports (sip and pjsip (udp
and tcp), rtp (udp)) is configured. IF a call goes through, nearly
everything is working (audio only incoming, but that is another
issue).<br>
<br>
STUN is configured. FreePBX Firewall is disabled.<br>
<br>
Kind regards,<br>
