Interactions for Chained Call Forwarding

Last Updated : Oct 30, 2012 |

  • Chained Call Forwarding is only valid, if the calls stay on the local switch. Once the call leaves the local switch the Call Forwarding Chain is broken.

  • When a call is forwarded to a busy or no-reply station in which Enhanced Call Forwarding Busy is active and Chained Call Forwarding is enabled for call override, the call is forwarded to the called station for all internal and external calls.

  • When a call is forwarded to a busy or out-of-service station in which Enhanced Call Forwarding Busy is active and Chained Call Forwarding is enabled and reaches the maximum number of call forwarding hops with no call coverage path set, the caller hears a busy tone.

  • When calls are forwarded using chained call forwarding the calls to the forwarding station from the origination station follow a call coverage path.

Call forward override

If the Call Forward Override feature is turned on, and a call terminates at an already visited station for that call as a part of the call forward chain, the call is not forwarded. Instead, the call continuously rings at that station to avoid loops while traversing the chained call forward path.

For example, Station A has activated call forward feature to Station B, Station B to Station C, and Station C to Station D. In this case, if Station A gets an incoming call and forwards the call to Station B, then Station B forwards the call to Station C, and Station C forwards the call to Station D. Eventually the call is answered by Station D, which transfers the call to Station A. The call continuously rings at Station A and is not forwarded to Station B.
