Procedure 15

Configuring the main office

Use Element Manager or the Command Line Interface for this procedure. Refer to IP Peer Networking: Installation and Configuration (553-3001-213) for details.

1Configure the main office emergency trunk (CAMA or PRI).

Configure either analog CAMA or digital PRI to correctly signal the call identification.

ESA overrides all restrictions. Configure the trunk with restrictions so that other features cannot access the trunk.

2Configure the Virtual Trunk using the procedure from IP Peer Networking: Installation and Configuration (553-3001-213).

The Virtual Trunk must be configured to enable emergency calls originating from SRG IP Phones registered at the main office to reach the branch office.

3Configure ESN.

ESA uses a route number rather than ESN route list index. However, ESN is required at the branch office.

4Configure Emergency Services Access (ESA) in LD 24.
