> When direct media is enabled and a pjsip channel is answered a race would occur between the handling of the answer and bridge setup. Sometimes the media negotiation would take place after the native bridge was setup.  This resulted in a NULL media address, which in turn resulted in Asterisk using its address as the remote media address when sending a reinvite.  This patch makes the chan_pjsip answer handler synchronous thus alleviating the race condition (the bridge won't start setting things up until after it returns).
