Calls, including to echo, drop in 30s

FreePBX Configuration
1

Hopefully this is just something I’ve missed. I stood up a new freepbx image to do some Asterisk dev, but I wanted to get calls working between extensions first. I created two extensions, and tried to get a call between them. Signalling went through, and the receiver had two way audio, but the initiator of the call had no received audio. Call dropped after 30s. Then I found the echo (*43) application. Calling this gave me a similar result-the call dropped in 30s, but I could hear audio coming back from the app. Here’s a wireshark trace from the client side:

The freepbx log doesn’t really show much else (no reason for the BYE). Some other notes:
-In the SIP settings, I have 10.0.150.0/24 and 10.0.130.0/24 as local networks
-Extensions were created as pjsip

What seems odd to me is that the PBX keeps re-sending the 200 OK, but that the client doesn’t seem to accept it and nail the call up. I’ve reproed the same behaviour with both Microsip and X-Lite softphones, so I don’t think it’s the endpoint. I’ve also tried different combinations of RTP Symmetric, enable ICE, and Direct Media in the extension settings. Anything else I should try?

Confirm that after changing Local Networks in Asterisk SIP Settings, you did Submit, Apply Config and then restarted Asterisk (or the entire server).

If that’s not it, try disabling ICE on both the client and Asterisk.

If still no luck, post details about networking between 10.0.130.x and 10.0.150.x, as well as another log.

Your client is giving a public IP in its Contact header, a private IP in its Via header, and a different private IP in its SDP.

But it looks like all of the traffic is on 10.0.130.x (your phone) and 10.0.150.x (your Asterisk server).

Make sure Asterisk has 10.0.130.x as a localnet. (Set this in Asterisk SIP Settings in FreePBX)

Then disable STUN on your microsip client (not needed here).

See if you can figure out where the 192.168.1.114 address in your SDP is coming from.

OK, this is strange. I had this configured as a localnet, and I was getting this issue. Just to rule it out, I restarted the whole freepbx VM again, and everything started working.

Then I tried removing the 10.0.130 subnet from localnets and restarting. Failed-which means that was the fix. Then I added 10.0.130.0/24 to localnet and applied without restarting…and it worked? I expected that if the issue was a restart that it’d take a second restart to apply, but apparently not?

In any case, it works now. Thanks for the quick replies.
