Hi; I am still not able to compile and link pjmedia.I have asked this query earlier also and with reference to your earlier reply: You're trying to link with lots of stuffs which are not available in pjsip's Symbian port (for example, Speex, PortAudio, etc.). can i remove functions related to speex and portaudio referred in pjmedia in pjsip 0.8.0 to establish audio transmission.Will this affect our attempt to achieve audio call setup using symbian_audio.mmp instead of null_audio.mmp. Thanks in advance. regards Saurabh Agarwal Now you can chat without downloading messenger.
