Place a call from phone 55661000 to phone 88995000. The local SIP server on Router C removes
the area prefix 8899 from the called number, and alerts internal phone 5000. Pick up phone 5000.
The call is established.

Network requirements
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.
