Network requirements
As shown in Figure 643, Router A, Router B, and Router C are located at place A, place B, and place
C, respectively. They are all connected to the SIP server to allow subscribers to make SIP calls.
When VoIP links fail for some reason, PSTN links that provide backup for VoIP links can be
automatically brought up. It is required that subscribers whose telephone numbers beginning with
1100 at place A can originate calls to place B while subscribers whose telephone number beginning
with 1200 can originate calls to both place B and place C.
