Asterisk after migrate to PJSIP no ring and unavailable

Asterisk Asterisk SIP
1

I have an Asterisk server in one Amazon EC2 running in Ubuntu server LTS 16.04 and migrate to use PJSIP protocol, before I was using SIP and was working properly, now after migration the extention shows like connected but unavailable, the calls doesn’t ring with exception one extension.

I have 3 extensions created and only one rings and show as Available, the 3 extensions have the same settings.

6001 work, available and ring
6002 doesn’t work, unavailable and doesn’t ring
6003 doesn’t work, unavailable and doesn’t ring

Please provide the actual endpoint configuration for the other endpoints, as well as network information - are they remote and behind NAT? You should also provide SIP trace of the inbound registration and call attempt using “pjsip set logger on”.

Don’t create a “type = contact” in the configuration, and don’t set an empty “contact=” in the AOR. Your “type=identify” section also does nothing and can be removed.

ok jcolp, thanks.

I corrected its, but didn’t work yet… I put these parameter to check if it works, but no success and I leave there.

More any sugestion?

6

As I mentioned previously you need to provide an actual SIP trace and information about the network layout.

7

Yes, I have my cloud server and the extension is working behind a NAT, all extensions.

8

You have no NAT support enabled for the endpoints. They would need “rewrite_contact=yes” and “rtp_symmetric=yes”.

9

great, now worked in parts, the endpoints are available and ring, but the calls are without audio.

10

Then you’ll need to look at the signaling to see where media is being told to go, check any firewalls, look at “rtp set debug on”.

11

the range of rtp ports seted is from 10000 to 20000 and it is opened in my firewall, was working well with SIP.

bellow the trace with rtp debug on

Your Asterisk is not receiving RTP, so you need to look at the SIP side to see where it told the endpoints to send it. As well for future reference there’s documentation on the wiki[1] for this kind of stuff, including how to set up PJSIP if it is behind NAT and what to do when endpoints are behind NAT.

Audio solved, just was missing the parameter media_address in the endpoints.

Thank you very much jcolp
