There are so many SIP stacks and media stacks available as open source. So are the IM and softphone clients. But, the vast majority of them do not secure the text and/or voice communication. As a result, it would be certain as a differential factor if the PJSIP supports SRTP and ZRTP. There is already an open source implementation (inside GNU ccRTP) for ZRTP, which has been used in Twinkle and minisip projects, and in the next release of Ekiga.

Thanks for the vote Paul! As you can see from http://www.pjsip.org/trac/roadmap we do have SRTP on our radar. Keep the suggestions and feedback coming, please...
