Trunks, stations, or agent endpoints obtain location numbers as follows:

• Non-IP phones and trunks inherit the location number from their connected hardware. For example, a non-IP phone inherits its location number from a cabinet, remote office, or media gateway.

• IP phones indirectly obtain their location numbers when the location numbers are administered on the Network Region screen. This screen applies location numbers to all phones in the same network region.

  If the location field is left blank on the Network Region screen, the IP phone assigns its location from the CLAN board located on the cabinet or gateway where the phone is registered.

• H.323 IP and SIP phones receive the location defined on the Location field of the Station screen. This assignment overrides other location assignments.

• IP and SIP trunks obtain their location from the cabinet containing the CLAN or NIC that the trunk is signaling through.

If none of the above applies, location 1 is used as the default.
