{ Make a call from the external number 55661000 to the internal number 88995000. The local SIP server
Router C removes the area prefix 8899 from 88995000 to convert it into the internal short number 5000. Then, the
local SIP server alerts Phone 5000, and both parties can communicate after Phone 5000 is picked up.
Configuring a call route
Network requirements
As shown in Figure 57:
• The internal numbers of a company are four-digit long and the area prefix is 8899.
• External phone 55665000 attached to Router B is not registered with the local SIP server on Router
C.
• Internal phone 1000 attached to Router A is already registered with Router C.
When a user in the company dials the external number, the local SIP server will route the call according
to the configured call-out route and add area prefix 8899 to the calling number.
