Notes
Maximum Number of Triggers:
If aurora
Duet
receives a frame containing a matching
parameter which it cannot reconcile with a currently
running trigger, aurora
Duet
starts a new trigger. The
maximum number of triggers which can run at a time is
50.
CPN and Cause Code Capture Triggers:
Due to the way aurora
Duet
stores frames in its buffer, it
may not be able to trace back to the Setup message which
signals the start of the call. Therefore, in some cases, data
may be lost.
B-Channel Capture Trigger:
Automatic capture is triggered as soon as a matching B
Channel value is received. Therefore, capture is still
triggered even if the actual channel used for the call
changes. Automatic capture is also triggered if, later in
the call establishment procedure, a call is assigned to a
channel which matches the B Channel trigger. The
following examples illustrate this:
Example 1 - you specify a capture trigger of B Channel 2:
aurora
Duet
receives a Setup message for B Channel 2 and
automatic capture is triggered. However, this channel is
unavailable and the call is established on B Channel 1 -
automatic capture is still triggered.
Example 2 - you specify a capture trigger of B Channel 2:
A call is received for B Channel 1, but this channel is
unavailable, so the call is assigned to B Channel 2 and the
capture trigger is activated.
Setting the value of the Capture Trigger
For some capture triggers, you need to specify a value -
