CSR Basics

This section describes the basic operation of CSR.

After CSR is started, it registers with the gatekeeper connected to a network. Any one or a combination of the following registration messages are used:

•ARQ

•LRQ

•DRQ

•BRQ

•URQ

•RAI

•LCF

•LRJ

•IRR

The gatekeeper responds with any of the following messages:

•ANI

•DNIS

•Source carrier

•Destination carrier
