> Components: pjproject/pjsip

> 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:
