If Extension to Cellular users cannot receive calls on their cell phones, follow these procedures in the suggested order to isolate and fix the problem. After each step, verify if the problem was fixed. Make a call to the mapped cell phone through the office telephone number.
Procedure
Verify that you can call the cell phone from the switch.
This call also verifies that the service contract with the cellular service provider (CSP) is active, and that the user gets good coverage in that area.
Make the direct call to the published number of the cell phone. When making this test call, wait until the call rings the cell phone which verifies that there is coverage. Or, wait until the call goes to the cellular voice mail. This test call verifies that the service is provided even when there is weak coverage.
Enter status station.
Verify the office number that the Extension to Cellular telephone is mapped to. Verify that SAC or Call Forwarding has not been activated on the principal extension.
For the Extension to Cellular extension, enter status station<extension>.
Check the following states:
The service state is in service/idle. If not, enter release<extension> to put the extension back in the active state.
The Extension to Cellular state is enabled on the Status Station screen. If Extension to Cellular is disabled, ask the user to enable Extension to Cellular for the principal office number.
On the Stations with Off-PBX Telephone Integration screen, verify that the entries in the following fields are correct:
Mobility Trunk Group
Dial Prefix
Calls Allowed
Cell Phone Number
Check the ARS Analysis table and ensure that there is an entry to route the cell phone number over an ISDN trunk on the switch.
If the Mobility Trunk Group is ars or aar, verify that no FAC number is included in the cell phone number field.
Enter list ars route-chosen 1234567890, where 1234567890 is a 10-digit cell phone number, to verify the type of routing used to route the call.
Check ARS digit conversion to verify that no unwanted characters are added to the dial string.
If the problem cannot be corrected by following this procedure, escalate the issue to Avaya Remote Technical Services (RTS). In addition to the preceding checks, verify with the technician that the Extension to Cellular station can receive incoming calls.
