Evolution from circuit-switched to IP
90 Avaya Application Solutions IP Telephony Deployment Guide
Consolidating remote site servers into an S8700 system requires a G700 or G350 Media
Gateway with an S8300 Local Spare Processor (
Figure 36: S8700 / G700 / G350 system with
S8300 as Local Spare Processor (LSP)
). In the event of a network or processor failure, the
S8300 server takes over active call processing and gateway and endpoint management for the
remote site, allowing continued operation with no loss of features until the outage is repaired.

Because the G700 and G350 rely on IP Telephony technology, this option is especially
attractive to customers who decide to use a majority of IP endpoints at the remote site. This
solution will, however, continue to support analog endpoints and DCP endpoints. Analog trunks
and ISDN trunks are also supported. To decrease operational expenses, the circuit-switched
trunks back to the main site can be replaced with IP trunks.
