For the above warning I’ve removed all the codecs and enabled these two but still the call hangs up on answer. The new section of the log is below. Your assistance would be greatly appreciated.

Still a codec issue.

Google “Asterisk No path to translate from” you’ll get a ton of posts.

Also, in the future, please post pastebin links, or select preformatted text. Otherwise, it’s very hard to read.

Thanks. Not sure if the pastebin is embedded but it’s here:

Still get the messages despite changing my phone to use PCMU as the prefered codec. I believe that is the same as ulaw.

Changed the sip settings to only have ulaw as well as the trunk but still the above. Am I missing a setting?

6

The elephant in the room is why are you allowing anonymous calls into your PBX? That should be stopping your calls way before the phones get involved. This is a trunk issue and with the recent spate of PBX Sangoma is seeing from Iran, Turkey, and Russia, it would really be a good idea to get your configuration under control.

7

Thanks. Yes, I will change once I’ve got things working. In the mean time why am I getting g723 references when I’ve disabled these codecs in my trunk and route?

8

…and your phone?

9

Grandstream DP750.

10

From the manual

Preferred Vocoder Configures vocoders in a preference list (up to 8 preferred vocoders) that
will be included with same order in SDP message. Vocoder types are G.711
A-/U-law, G.722, G.726-32, G.723, G.729, iLBC and OPUS

Make sure only G.711 is enabled

11

On the phone I only have PCMU enabled.

12

I would use sngrep and see what codecs are being offered in the SDP negotiations and by whom, g723 is not usually used by VSP’s but maybe this one?

At the Asterisk command prompt, type
pjsip set logger on
make a failing incoming call, paste the Asterisk log for the call (which will now include a SIP trace) at pastebin.freepbx.org and post the link here.

Thank you.

680513 [2020-11-05 17:46:03] VERBOSE[15996][C-00000004] pbx.c: Executing [441827818721@from-sip-external:1] NoOp(“PJSIP/anonymous-00000006”, “Received incoming SIP connection from unknown peer to 441827818721”) in new stack

OK, so FreePBX did not recognize the call as from your SIPgate trunk and it applied the default codec list, which apparently included G.723 at or near the top.

In Asterisk SIP Settings, General tab, scroll down to the Codec list, uncheck everything but ulaw and alaw, move alaw to the top, Submit, Apply Config, restart Asterisk and test.

You should also fix your trunk settings, because allowing anonymous calls is a security risk. Set the Match (Permit) field to include all IP addresses from which the provider can send you calls.

The trunk should be Diamondcard which is a pjsip trunk. My sipgate trunk is disabled at the moment.
I already only had ulaw enabled in the main general area but I have enabled u and a and moved alaw to the top.

Kind regards.

In your DiamondCard pjsip trunk, set Match (Permit) to
69.65.34.202,69.65.34.219

and retest. With luck, it will at least recognize the trunk. If you post a new log, you must reissue
pjsip set logger on
because a reload cancels that setting.

Thanks. Done. Results here:

Diamondcard’s documentation seems to have a problem.

I looked at http://wiki.diamondcard.us/podwiki?page=PersNumbersSup
and found that sip.diamondcard.us has SRV records pointing to sip.diamondcard.us [69.65.34.202] and sip2.diamondcard.us [69.65.34.219]. But your call came from 69.65.34.216.
So, based on https://whois.domaintools.com/69.65.34.216
change Match (Permit) for the trunk to 69.65.34.192/27 and retest.

Thanks again Stewart.
That fixed the issue!

I’ve attached the log file below as I’d really like to know what the problem was for future reference and of course to help others should they experience the same.

Why the reference to codecs?
