I know pjnath is missing in the Getting_started wiki, and that's intentional, since the instruction on that particular part of the Wiki only applies for pjsip version 0.5.10.1 or older, which lacks pjnath of course. > Although it now builds fine I still have a question :-) > > Why is libpjsdp not needed? I thought by using pjsua (which is a > complete VoIP stack) I thought that SDP functions will be needed too? Pssst..! libpjsdp is secret, and undocumented, so don't tell anyone! The SDP stuffs are built into two libraries, pjmedia and pjsdp. If application just want to use the SIP stack and *not* the media stack, it can link with pjsip and pjsdp (and not with pjmedia). For typical VoIP application that want to use both SIP and media stack, it can link with pjsip and pjmedia, and it'll get the SDP stuffs from pjmedia. cheers, -benny > thanks > klaus
