It seems the packets are coming but rejected by any component of pjmedia stream. (which most suspected would be codec parser or jitter buffer) There is a scenario, empty jitter buffer + restarting RTP timestamp, which may causing jitter buffer ignoring packets, this only happens on the older version of jitter buffer and it seems you are not using the latest SVN. So please update your source from the latest SVN. Just to make sure that the problem is not in G.729 implementation, please also try to call using PCMU codec.
