Typically this is done in its own thread. When a RING is +detected, the backend should create a channel structure and then call +ast_pbx_start() on that channel, which will create a thread to monitor +that interface. At this point, the PBX and/or applications it launches +will manage the interface, and it need not be monitored by the +aforementioned thread. When the applications are finished, the requisite +hangup function will be called, at which the channel can be considered to +be no longer valid, and the thread that controls it will imminently be +terminated. + |
