[SIPForum-discussion] DTMF

[praveen subbarao]

Hi All,

I have a doubt in SIP. Supposing that a SIP client wish to communicate with a PSTN client, then he will input the PSTN number. 

In SIP, where & how the DTMF information is carried. Which are the headers responsible for this? I rquest to knidly clarify.

Regards,
Praveen
