Issue

An incoming analog line rings several times before presenting the call to an extension.

Actions

1. 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.
2. 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

1. 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.

2. From IP Office Manager, change the configuration to Loop Start only, as follows:

1. Log on to IP Office Manager and open the system configuration.
2. From the configuration tree, select Line and double-click the analog trunk in question.
3. On the Line tab, change Line SubType to Loop Start .

Alternatively, have the central office enable CLI/ICLID on the trunks.
