Network requirements
As shown in Figure 640, 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.
