Hi Michael, Depending on the PBX configuration (most PBX have this setting), the RTP might be established between the terminals directly or through the PBX. I thought it could be possible the softphone cannot find a network route to the Aastra telephone. But, once it works with phoner, there is a network path anyway. If you send one capture file for PJSUA and one for phoner (containing SIP message flow with SDP, which contains the RTP negotiation details), it might possible to figure out what is going wrong with your environment.
