|sip_call||yes||Begins when a call starts and ends when the call hangs up.|
|sip_call_dial||no||A SIP call is being dialed and not yet ringing.|
|sip_call_ringing||no||A SIP call is ringing.|
|sip_call_connect||no||A SIP call connected (got picked up).|
|sip_call_hangup||no||A SIP call was hanged up.|

Most SIP events have the following common parameters :
|from_display||string||Display name of the caller.|
|from_uri||string||URI of the caller.|
|to_display||string||Display name of the callee.|
|to_uri||string||URI of the callee.|
|call_id||string||Call-ID of the call.|
This event is generated for each call. It begins when an INVITE is sent and ends when a timeout or a BYE is seen.
|trying_duration||uint32||Duration of the trying state in seconds.|
|ringing_duration||uint32||Duration of the ringing state in seconds.|
|connected_duration||uint32||Duration of the connected state in seconds.|
Additionally the sip_call event has all the common parameters described above.
This event is generated when an INVITE is sent. It only has the common parameters described above.
This event is generated when a 180 Ringing event is received. It only has the common parameters described above.
This event is generated when a 200 OK event is received. It only has the common parameters described above.
This event is generated when a BYE event is received or when the call timeout occurs. It only has the common parameters described above.
This event is generated when a INFO packet with content type application/dtmf-relay is received. It has the following parameters :
|signal||string||The key being pressed.|
|duration||uint16||Duration of the key press in milliseconds.|
|dialog_timeout||uint32||300||Timeout for SIP dialogs.|
|dialog_connected_timeout||uint32||10800||Timeout for dialogs which established a call (UDP only).|
