    Chapter 4 CS 1000 considerations In the event that the IP Phones at the branch office lose the connection to the main office CS1000 call server for any reason (WAN failure, main office call server failure, main office Signaling Server failure), the SRG50 reverts to local mode automatically. Essentially, when VoIP connectivity is lost, each IP Phone loses its Reliable UDP (RUDP) connection with the main office terminal proxy server (TPS).

    This test is invoked from any IP Phone at the branch office. Nortel recommends testing local mode operation after changing the provisioning for a telephone on the SRG. To ensure that users do not forget to resume normal mode operation, the SRG redirects the telephone to the main office to return the telephone to normal mode.

    Chapter 4 CS 1000 considerations ACR for NBWM allows a station-to-station call (that is, a call that does not use a trunk) to overflow to traditional routes. Overflow can occur if there is insufficient interzone bandwidth available to carry the call, or if the QoS has degraded to unacceptable levels. The feature applies to station-to-station calls between a branch office and main office as well as from one branch office to another branch office, provided both stations are registered to the same main office.
