Hi Nina, AFAIK, PJSIP supports incomming DTMF either on SIP or RTP (TFC2833), but not inband DTMF, e.i in the speech signal it self. For outgoing DTMF you can either use SIP/RTP or generate DTMF with the tone generator. So I think that the issue migh me that the remote party doesn't support the method you use to generate DTMF. You can use PJSUA to test this.

After some users recommended pjsip and told me that it supports dtmf, i started using it. It took some time but now I can use the dtmf. I felt well already. However now I found out that it does not really work! It works only with incomming calls. Whenever a call is by pjsip to another phone, it fails and does not recognize any pressed digit. I saw the other thread for the same problem without a solution there. Not even a reply. I hope there is someone who can help on this bug(?).
