I have a question if the DTMF ws transmitted thogh SIP IFO or RFC wouldnt it always transmit it as Inband at the same time as when you click DTMF it makes frequency and that will be transmitted with the RTP.

How to see what number the person you are calling dialed?

This part is not the DTMF we talk here. For SIP calls, it usually takes the called number in the request- line of the INVITE packet. For example, INVITE: XXX@1.1.1.11. Here is the number you dialed. To analyze the INVITE packet, try to refer to this video: kzfaq.info/get/bejne/fN-WnZuh16fVook.html

Hi There, the wireshark could not recoginze the inband DTMF directly. Firstly output the audio followed by this article: support.yeastar.com/hc/en-us/articles/360038351294 Then follow this article to check the DTMF wave: support.yeastar.com/hc/en-us/articles/360038790193
