Issue
An incoming analog line rings several times before presenting the call to an extension.
Actions
-
If the analog trunk is configured to wait for caller ID (CLI/ICLID) information from the central office and the information is not being provided, there will be a delay between the time the line/trunk rings and the call being presented to the extensions.
-
Check the system configuration in IP Office Manager and ensure the analog trunk parameters are correct and that they match those provided by the central office.
Procedure
-
In the Analog Trunk Summary, click the
Alarms
tab:
If the central office is not providing Caller ID information, System Status displays No Caller ID received under Error Description.
-
From IP Office Manager, change the configuration to Loop Start only, as follows:
-
Log on to IP Office Manager and open the system configuration.
-
From the configuration tree, select
Line
and double-click the analog trunk in question.
-
On the
Line
tab, change
Line SubType
to
Loop Start
.
Alternatively, have the central office enable CLI/ICLID on the trunks.
