AR2200 Series Enterprise Routers

2, High-Quality Voice Service
The AR2200 provides
24GE interface cards
to implement high-
density GE access.
This interface card
facilitates network
operation and
maintenance and
protects customers'
investment.
The AR routers have built-in PBX,
which supports the enterprise main
number, IVR, and bill query functions
to enhance corporate image and
improve enterprise communication
efciency. The AR2200 is located in
a branch to provide the intelligent
dialing function. When a fault occurs
on the WAN, the PSTN network is
used as a backup for calls. When the SIP server at the headquarters is unreachable, the built-in local SIP server of the
AR2200 implements communication between the branches and communication between branch and PSTN network.
This ensures reliability of the voice service.
As a voice gateway for enterprise networks, the AR2200 can function as an IP PBX or SIP gateway.
