[SIPForum-discussion] INFO message in SIP

[Banda, Srinivas (Srinivas)]

Hi Sadashiv,

The purpose of INFO message is to send the mid-call events i.e DTMF digits.
So INFO will be used as In-Dialog request for mid call related events. In the scenario mentioned by you the Dialog has not yet established.

Regards
Srinivas
