As the converse-on vector step does not include any information on the queue position and the wait time for the call at the remote end, Voice Portal Call Back Assist does not work with BSR Local Treatment.

In a multisite BSR configuration, a call that arrives at a local Communication Manager server can be rerouted to a remote server located in a another part of the world. With BSR local treatment for calls queued remotely over IP (SIP or H.323) or ISDN trunks, you can provide local audio feedback to calls while calls wait in a queue on a remote server.

The feature provides the following benefits:

• Bandwidth savings for IP calls.

• No audio quality concerns that occur when music is sent over WAN that use low bit-rate codecs.

• Centralized management for announcements and other call treatment.
