Hi all, I have an issue with asterisk 13 and pjsip. I guess it is somehow Firewall related, but I’m unsure.
A registration to Sipgate is established successfully:
pjsip_sipgate/sip:sipgate.de:5060 pjsip_sipgate Registered
Calling the registered number is even successfully shown in asterisk (it is a freepbx installation). But when doing a second call the number is busy (“provider” busy, I
don’t see anything in asterisk verbose mode). Sending a pjsip unregister results in the following messages:
[2016-10-15 10:03:22] WARNING:
res_pjsip_outbound_registration.c:761 schedule_retry: No response received from ‘sip:sipgate.de:5060’ on registration attempt to
‘sip:email@example.com:5060′, retrying in ’60’
— Contact pjsip_sipgate/sip:firstname.lastname@example.org:5060 is now Reachable. RTT: 434.393 msec
== Endpoint pjsip_sipgate is now Reachable
so it is somewhat clear, why i get a busy, because the endpoint is not reachable. But WHY is the endpoint not reachable?
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).
STUN is configured. FreePBX Firewall is disabled.
Kind regards, andre
