摘要:
An improved call forwarding arrangement where forwarded calls receive different terminating treatment from non-forwarded calls, for example providing a readily detectable, distinctive alerting signal for forwarded calls or completing only forwarded calls to a station and denying or forwarding other calls without requiring any customer involvement. The arrangement provides an improved call forwarding service for customers with advanced station display capabilities and, in addition, allows selective answering of only forwarded calls by customers that have conventional, analog station equipment. Both switch-based and station-based implements are disclosed.
