Networking consideration
A fault condition can occur if IP Phones use a different route to the main office than that used by the SRG.
CAUTION — Service Interruption
If the network is planned so that IP Phones use a different route to the main office than that used by the SRG, a fault condition can occur. When the SRG can ping the main office but the IP Phone cannot ping the main office due to a network outage, an IP Phone registration can force the telephone into a cycle of registering locally, being redirected to the main office, rebooting, and then registering locally again. When this cycle occurs, further diagnose the network outage.
Capacity
Each CS 1000 main office can support up to 255 branch offices, which can be made up of any combination of SRGs and MG 1000Bs. SRG50 supports up to 32 IP Phone users. However, since all IP Phones register with the main office, the governing factor is the maximum number of IP Phones that can be supported at the main office. This means the total number of IP Phones in all offices can be no greater than the capacity of the main office. Refer to one of the following documents to determine the total number of phones your system can support:
•Communication Server 1000S: Planning and Engineering
•Communication Server 1000E: Planning and Engineering
•Communication Server 1000M and Meridian 1: Large System Planning and Engineering
•Communication Server 1000M and Meridian 1: Small System Planning and Engineering
