End of Call Detection
If a call through DISA is routed to a trunk, DISA can be used to detect the end of the call. This function can
be disabled through system programming. If disabled, DISA is released when the trunk-to-trunk connection
is made.
The following three types of tone detection can be enabled for each trunk group to disconnect a
trunk-to-trunk call via DISA.

Trunk-to-Trunk Call Duration Limitation
For a call between two outside parties, even if end of call detection cannot be performed, the call can be
disconnected by a system timer. (
®
1.11.8 Trunk Call Limitation) If the timer expires, the line will be
disconnected unless the originating caller extends the time by sending any DTMF signalling. The caller
can prolong the call duration within the preprogrammed time period and preprogrammed number of times.

Automatic DISA Activation
DISA can be set through system programming to automatically activate for the following types of
trunk-to-trunk call, to enable detection of the end of the call.
–
When a trunk call is forwarded to another trunk
–
When a trunk call is transferred to another trunk
–
When a trunk call to an incoming call distribution group is answered by an outside destination member
Before the call is made, the PBX confirms that a DISA port is available. If no DISA ports are available, the
call is not routed to a trunk. For transferred calls or calls to an ICD Group, if the DISA port has become
unavailable when the trunk-to-trunk conversation is actually established, the call is established without
DISA.
When using this feature, the Trunk-to-Trunk Call Limitation timer should be enabled. In addition, prolonging
the call through DTMF signalling is not available.
•
DISA Call Transfer from Outside Destination
An outside party such as a cellular phone can transfer a trunk call to an extension at the PBX by pressing
"#" + extension number, if DISA is connected by the Automatic DISA Activation feature. This feature can
be enabled or disabled through system programming.
