IP telephones redirection

Once an IP telephone at the SRG is configured (see IP telephones setup and configuration on page 53), it automatically registers with the SRG (S1). To configure an IP telephone for redirection to the main office call server, SRG-specific datafill is required. The SRG-specific configuration includes:

•IP telephones numbers and models on page 47

•S1000 IP Terminal Details panel on page 48

To configure SRG using SIP trunks, CS1K must accept the end point as an H323 and SIP entity and accept it as h323 and SIP endpoint. You do not need to enter BCM SRG50 configuration under Telephony Resources > IP Trunks > H323 Setting. The entire configuration for SIP trunking must be entered under SIP settings, SIP Proxy, SIP media parameters, SIP URI Maps and SIP Authentication.

IP telephones numbers and models

SRG DNs are assigned to IP telephones using Element Manager. Redirection to the main office requires configuration at the SRG to associate the SRG DN with the CS 1000 terminal number (TN) and the corresponding branch user ID (BUID).

When the CS1000 TN is configured, the IP telephone model forms part of the record. At the SRG, the actual IP telephone configured to an SRG DN must be the same model that is configured in the TN record that is associated with the SRG DN.

The table IP telephone numbers and models on page 47 provides a record of the CS 1000 TN and BUID, the SRG MOTN and DN, and the model of phone, to facilitate installation and provide a permanent record of the configuration.
