#### Description <!-- Describe your changes in detail --> some user agents send a=sendonly as a session attribute and is_audio_on_hold() returns false when it should return true.

#### Changes - changed sdp_session_cell struct in sdp.h to add sendrecv_mode and is_on_hold - changed parse_sdp_session in sdp.c to iterate session attributes and call extract_sendrecv_mode for assigment to session - changed ki_is_audio_on_hold in textops.c to look for session sendrecv_mode if its not set in media
