Call-by-Call Service Selection

Last Updated : Oct 30, 2012 |

Using the Call-by-Call (CBC) Service Selection feature, a single ISDN trunk group can carry calls to several services. Call-by-Call Service Selection eliminates the need to dedicate each trunk group to a specific service. With Call-by-Call Service Selection, you can set up various voice and data services and features for a particular call.

Call-by-Call Service Selection provides the following benefits:

  • Cost reduction. Since many services share the same trunks, this feature can reduce the total number of trunks that you must use.

  • Improved service. Features and services are less likely to be blocked.

  • Simplified networking. This feature simplifies network engineering. Instead of a per-service basis, you can analyze trunking needs based on total traffic.

  • Tracking. Call-by-Call Service Selection calls are measurable.
