    55The redirection in this article is about processing SIP redirect (3xx) response in outgoing calls, and not about sending redirection/3xx response. Sending 3xx response in PJSUA-LIB is easy; just use {{{pjsua_call_hangup()}}} and give the new targets in Contact header in {{{msg_data}}} parameter.

     126=== Type of Event in PJSIP's on_state_changed() and PJSUA-LIB's on_call_state() callbacks ===

     128It's good to remind here that while these callbacks traditionally only emits {{{PJSIP_EVENT_TSX_STATE}}} event, technically it can emit other types of events. Now especially with the pending redirection feature, a {{{PJSIP_EVENT_USER}}} event may be passed to these callbacks. Hence application should check for the event type before accessing the event structure.
