[SIPForum-discussion] RFC2833 dtmf with inband dtmf

[Saurabh Shah]

Yes, you can send both at the same time. But remote peer will detect DTMF
only from the type which is negotiated in offer-answer.

Subject: [SIPForum-discussion] RFC2833 dtmf with inband dtmf


I have searched the RFC's but I have not found the answer to my question. 

Is it normal to transmit inband dtmf (audio frequencies) while also using
RFC 2833 DTMF events?

I am receiving calls from Level 3 with both being used.
