Hi all,

           I am trying to transcoding for a specific DTMF telephone-event
from opensips +rtpengine. I am using opensips 3.2.12.

Here's Call scenario :
Initial INVITE SDP ---> OpenSIPS

*       a=rtpmap:105 telephone-event/16000       a=rtpmap:100
telephone-event/8000*

>From opensips i want to add below DTMF payload 101 because B party is
accepting this DTMF payload type.
* a=rtpmap:101 telephone-event/8000 *i am using below code.
*       rtpengine_offer("transcode-telephone-event/8000");*

By using this function opensips does not transcode specific DTMF payload
101.

Is there any way to achieve this transcoding ?
Please let me know.


Regards,
Vinayak Makwana
