How to integrate AMR in asterisk 20
There used to be some in-house developments and adjustments to Asterisk. At least some of them can no longer be downloaded, probably because these codecs are outdated.
I want to connect my asterisk to an IMS of the operator via the sip trunk when I establish the connection for calls the link is well established but the song does not come out I looked in logs at the SDP level I realized that the IMS from the operator sends me the AMR codec in the INVITE during the negociation or asterisk 20 does not have the AMR codec what should I do please
Can you show us a SIP trace?

It looks as if both sides offer one of the G.711 codecs. If you reduce your codec list to a-law, does it work for this configuration?
You could also list the installed codecs with core show codecs audio.
We did it it doesn’t work
But the SIP trace should tell you what doesn’t work.
I noticed that in the asterisk installation folder there is a folder asterisk-20.2.1/third-party/pjproject and in this folder there is a file ./third-party/pjproject/Makefile.rules which has the --disable-opencore-amr argument
It seems that opencore-amr is expressly disabled in Asterisk 20. Is there a way to enable it?
on the other hand, is there a way to install opencore-amr independently and use it in Asterisk 20?
No. Asterisk doesn’t use any of the codec stuff in pjproject.
My Asterisk server is a vps with a public ip (194.34.XXX.XXX) connected to the operator by a vpn the operator’s local network is 172.14.23.X. The operator has a Sip (172.14.23.85) and an RTP (172.14.23.90).
I created a virtual address on my VPS (10.15.21.154). It is she who communicates directly with the operator.
Outgoing calls from my PBX to the operator are OK with OK sound. But incoming calls from IMS to my PBX are established but have no audio.
I nevertheless notice that the IMS sends me in SDP the AMR codecs which are not present in Asterisk 20. is this a codec problem or another problem? should I install AMR codecs? If yes, how ? what should I do in this case. that is the logs

I don’t have anything additional to add. I also advise you to not create multiple threads for the same thing. You now have two going for this same thing.
I apologize, how can I solve this sound problem please?
You haven’t given enough information to analyze the problem. Normally the problem is rooted in things outside of Asterisk, e.g. NAT, VPN or OSI Layer 8 related issues.
In practice it is usually a good approach to start with something that works and then incrementally add features until everything works. This is not possible here. In your case, I’d first try to resolve the codec problem locally and then make sure that there are no network problems.

ok I will do the tests and get back to you
