Time of Day

Because the SRG IP Phones, in Normal Mode, receive their clock information from the main office, which may be located in a different time zone, the main office must be able to provide a different time of day for these phones.

The time zone of the SRG is configured with the SRG zone at the main office. The time zone adjusts the main office time for display at the SRG. SRG telephones then display the correct time of the SRG, rather than that of the main office. For any configurations using centralized Call Pilot on the main office with one or more branch offices in separate time zones, the NMS package is required at the main office for the branch IP Phones.

SRG IP Phone to local PSTN calls

When an SRG IP Phone in Normal Mode dials a local PSTN number, the call is processed by the main office Call Server. The dialed digits are modified according to the dialing plan information configured in the zone for the SRG IP Phone.

The call is configured to be routed over the Virtual Trunk to the branch office. The SRG then tandems the call to the local PSTN.

Likewise, long distance calls can also be configured.

IMPORTANT!

If you use one Access Code for both local and long distance calls, and that Access Code is associated with a branch office zone, all calls (local and long distance) are routed through the SRG.

IP Phone to analog (500/2500-type) telephone calls

When an IP Phone in Normal Mode at the SRG calls an analog (500/2500- type) telephone of the same SRG, the call is processed at the main office Call Server. A Virtual Trunk route is selected according to the digits dialed. The call is routed over a Virtual Trunk to the branch office. The SRG processes the incoming Virtual Trunk call and terminates it to the local analog (500/
