CS 1000 and Secure Router 2330/4134
In a centralized CS 1000 call server architecture, the remote branches make use of the call
processing resources available at a central location, generally located at the corporate
headquarters. The survivable branch solution based on Secure Router 4134 (SR 4134) and
Secure Router 2330 (SR 2330) provides business continuity to the branch office in the event
of a WAN connection outage to corporate headquarters. With this solution, employees at the
branch office can continue to use SIP phones to place and receive intra-site calls and calls
over the PSTN, including 911 calls.
