[sip-comm-dev] Help Reagrding "Supprot For RTP DTMF"


#1

Hi

I wanna discuss about project idea "Support for RTP DTMF " which i saw on
Roadmap and i m hoping it to be in final list.

So regarding it the progress is..

1)I have read tutorials on RTP and also read rfc of RTP(Now i have
theoritical knowledge of rtp)....but not read much about rtcp.

  so is it req to have detail knowledge of rtcp also??

2)i have read drafts and other articles including rfc regarding rtp payloads
for dtmf .....

3)now i m trying to understand rtp coding implementation in java i.e
Understanding JMF RTP API 2.0

···

========================================================================================================

now i wanna know what basically is the aim of this Project idea.......

i.e now i think i have sufficeint knowledge to wok on this...so wanna know
Aim of this project......

and what other things do i need to know???

Also it would be very helpful .....if u plz guide me on how to proceed
further ...

Thanx in Advance

RTCP is actually defined as a part of the RTP RFCs. I don't believe it
is used in the transport of DTMF tones though, so I guess not being
familiar will not be much of a problem for what you'd like to do.

2)i have read drafts and other articles including rfc regarding rtp
payloads for dtmf .....

We'd like to have the possibility to configure SIP Communicator to send
DTMF tones over RTP. Right now we only support DTMF transport over SIP
INFO requests. We'd like to add RTP as an alternative DTMF transport.

and what other things do i need to know???

Also it would be very helpful .....if u plz guide me on how to proceed

You could have a look at the way we currently transport DTMF. This
should serve as an example of how to implement it over RTP.

Hope this helps!
Emil
