[sip-comm] Sending DTMF in a Sip Call ?


#1

Hi,

The best/right way is to have all of them implemented
and negotiate wich to use with the over UA, isn't it?

Think I remember we can say the UA capabiities in the sdp. Right?

How can I check out the patches?

Hello Edouard,

Hello,

at first you should define that type of DTMF you need.

audio inband, SIP INFO, rfc2833 ?

asterisk has support for all dtmf standart..

SIP INFO is an easy way, but not too much VoIP providers support it.

Two years ago I did some patches for RFC2833. Please check it and you can
add it to SipCommunicator.

Sorry, sorry for CODE style :-(((

I am afraid that there is currently no explicit handling of dtmf tones
in SIP Communicator. The feature is previewed but there is no guarantee
as to when exactly it is going to find its way in SIP Communicator.

Any volunteers? :slight_smile:

no, is not right.

SDP has support only for DTMF RFC2833 and the best way chouse DTMF
type now.

How can I check out the patches?

you should implementet an PCM packetizer in SIPCommunicator.

it's not easy way, but files that I have sent help you.

this is only for RFC2833!!!

Wbr,
