Description:	Crash occurs when both phones are using chan_pjsip & when one uses chan_pjsip and the other uses chan_sip. See below. h2. Using chan_pjsip h3. Setup: * Using chan_pjsip with two phones configured to allow directmedia for both endpoints. h3. Process: * Placed call from phone_A to phone_B * After ensuring two way audio and the RTP was being sent directly between the phones I pressed the Hold button on both phones simultaneously. This first attempt failed to place both on hold so I attempted again which put both phones on hold. The messages 'Started music on hold...' & 'Stopped music on hold...' started printing to the CLI non-stop. * On phone_B I pressed the Hold button to take phone_A off of hold at which point Asterisk crashed. h3.
