Call Scenarios and Applications

Call Sequence 2 shows an incoming call on an ISDN-PRI trunk delivered to VDN A. The ISDN trunk is configured for MultiQuest service. The incoming call indicates in its SETUP message that Flexible Billing is supported. The call is adjunct-routed. The adjunct sees that Flexible Billing is enabled, and routes the call to split 1. The call rings at agent 5001 and is answered. The ECS sends the response to the ASAI adjunct. The agent requests a billing change on the call, setting the new rate to $5/minute. This billing change is sent over the ISDN-PRI trunk, and the 4ESS accepts the change. The ECS sends the response to the ASAI adjunct.
