Hello, First of all I would like to apologize if this is not the right place for posting this. We are looking for an expert for migrating our mjsip code into pjsip based code. Currently we have a SIP useragent built on mjsip that dials a number and streams the audio to RTMP. Upon research we have come to know that mjsip does not support out of band or RFC dtmf tones. Since there are so less voip providers who support DTMF via sip info, we are looking to convert the application into pjsip with DTMF settings that can be altered in the configuration. If someone expert here is willing to take this , please contact me off list and we can discuss further. We are willing to properly compensate for the work. Thank you Linux Guy
