Finding DTMF type
I have a Wireshark capture with DTMF tones send. With rtpevent I can see the tones typed. I would like to find their type (inband, outband, RFC2833). Where can is see it?
add a comment
delayed answer, but in my case when i type
rtpevent
in the filter, i see the
RFC 2833 RTP EVENT
So this is the type
The fact that you see RTP events tells me that the DTMF tones are transferred by means of RFC 2833, or rather RFC 4733. Wether or not tones are also injected into the audio stream is for you to tell, they could both be there.
