Other configurations on the SIP trunk device and on other devices are the same as those described in
"Configuring a SIP server group with only one member server."
Verifying the configuration
1. When the SIP server with IP address 10.1.1.2 fails, the SIP server with IP address 10.1.1.3 takes
over communications between the private network and the public network. After that, the
communications recover.
2. When the SIP server with IP address 10.1.1.2 recovers, it does not take over call processing and
the SIP server with IP address 10.1.1.3 keeps working.
Configuring call match rules
Network requirements
The enterprise private network has a SIP trunk device. Router A1 and Router A2 are private network
devices, and Router B is a public network device.
• Users connected to Router A2 are not allowed to call public network users.
• All calls between the private network and public network are made through the SIP trunk device.
