DTMF Problem

[eduardofoliveira]

Version: LinphoneAndroid/4.6.14 (motorola edge 20 lite) LinphoneSDK/5.1.62 (tags/5.1.62^0) Desktop 4.4.8 - Qt5.15.2 Core 5.1.46-1-gb853a6bad

Problem: This problem occurs even in the desktop version.

If enabling PCMU and PCMA codecs in SDP is sent: a=rtpmap:96 telephone-event/8000

But in this way the dtmf does not work.

How can I change to: a=rtpmap:101 telephone-event/8000 ?

Another point is that a=rtpmap:101 telephone-event/8000 It is only sent in the speex 16000 codec

Is there any way to configure the dtmf payload?

Hi，you can try PayloadType.getSendFmtp and PayloadType.setSendFmtp
