             Summary: DTMF with direct media
                 Key: ASTERISK-30439
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30439
             Project: Asterisk
          Issue Type: Information Request
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 18.2.2
         Environment: Docker container
Alpine Linux 
Asterisk 18.2.2
            Reporter: Vitor Gomes Faria


Hi guys,
I'm having some difficulties establishing a topology using direct media.
The issue is when im using the direct_media = true the DTMF does not work.

My topology is:

SBC with PSTN 
Server 1 with Asterisk 18.2.2
Server 2 with Asterisk 18.2.2

Server 1 has an pjsip endpoint to SBC and another endpoint to a Server 2.
Server 2 has an pjsip endpoint to Server 1

Basically the call ingress by SBC endpoint in  Server 1 and forward to the Server 2.
When direct_media = false on all endpoints de rtp flow between three IPs and de DTMF works fine, but when i configure the direct media = true the rtp flow just between Server 2 and SBC (was expected and is what i want) but the DTMF doesent works.
The DTMF events does not apparece in a log of any server.

The DTMF type to all endpoints is rfc4733.

Below is the configuration of an endpoint:
