The use of timestamp in pjmedia_frame is currently underspecified, that's why we've scheduled https://trac.pjsip.org/repos/ticket/1290 to fix it. However, even now there are few places where the timestamp is being used, namely the timestamp of RTP packets to be put to jitter buffer and the timestamp in pjsip 2.0 for A/V synchronization purpose. Whether what you modify will cause ill effect depends on the nature of the modification I suppose. Benny
