managed from the main office. Instead, they are managed at each Branch Office. When a call is
between a digital telephone and an IP Phone, a DSP resource is required. Therefore, when digital
telephones are located in the Branch Office, allow for additional voice gateway channels to support
IP-TDM connections.

login enables a registration to another TN within the MG 1000B CP PM.
