Configuring caller group control
Network requirements
As shown in Figure 31 , areas A, B, and C call each other through the SIP server. Configure caller group
control on Router A so when the SIP server fails, the areas call each other though the public PBXs in PSTN
as follows:
• The phone numbers starting with 1100 in area A can only call the phone numbers in area B.
• The phone numbers starting with 1200 in area A can call the phone numbers both in area B and
area C.
