Thanks a lot. I decided to use the OPTIONS request together with the last dtmf received, so I don't need to use pjsua_internal.h. Since my application receives a lot of dtmfs from user (its a menu), I will reset a timer every time a digit arrives, so if the user doesn't send any dtmf for a certain amount of time I will send the OPTIONS request and wait a few seconds for the response.
