View source for SIP phone: Forward unattended call

{{AI}}
The Event Type [[Private Ringing Outgoing(Event Type)|33 - Private Ringing Outgoing]] can be used to forward unattended SIP calls. In order to work, it requires that the SIP device returns the SIP status "180 Ringing" when the phones starts to ring, and "200 OK" when connecting.

=== Configuration examples ===

====AMC10.55 and later====
:*The SIP phone is 9555.
:*When an intercom station calls 9555, the phone will start to ring, the ringing time is controlled by the "[[Exchange_%26_System_%28AlphaPro%29#Timers|Private Ringing Time" timer]] (30 sec default). If not answered, the call will time out, and the [[Private Ringing Outgoing(Event Type)|event 33]] is triggered. This event sets up a new call to directory number 9547 (which can be an intercom or another SIP phone). 
:*[[C KEY|$C]] is needed to "speed up" the disconnection, so that the [[DIAL DIGITS|$DD]] command is not lost during the disconnection tone

In [[AlphaPro]], go to [[Exchange_%26_System_%28AlphaPro%29#Events|Exchange and System -> Events]], press Insert and create the following event:
