Securing VoIP: SRTP Support in PJSIP

PJSIP now has SRTP support in SVN trunk (hurray!). For more information about compatibility, how to use, and what have been done, please see the SRTP wiki in
http://trac.pjsip.org/repos/wiki/SRTP

We’ve tested it against couple of phones that support SRTP and it looks good (apart from SRTCP, which one phone doesn’t support and the other we don’t think it implements SRTCP correctly). If you have phones which support SRTP, it would be great if you could give it a try, I’ll be thrilled to hear your result.

Enjoy it while it’s hot!

    Hi ,
    I was testing my SRTP implementation with the asterisk. I found out that while asterisk does convert the RTP packets to SRTP. It does not process RTCP packet and as a result the SRTCP packet fail to pass through.

    Unfortunately, the srtp library exhibits some portability problems – i.e. for sparc64 or arm one is likely to run into data structure alignment problems.

    As the report says, the problem is with the test suite, not with the library itself.
