Call Forwarding All
If calls to a digital telephone are forwarded to an analog Caller ID telephone using Call Forward All, the call to the analog telephone is not delayed since Communication Manager only delays alerting for the initial incoming call. However, the caller information may still display on the analog Caller ID telephone, if the caller information is received from the ISDN network before the analog telephone rings.
If calls to an analog Caller ID telephone are forwarded to another analog Caller ID telephone using Call Forward All, the call to the first analog telephone is not delayed since the call is immediately redirected to the second analog telephone. However, the caller information may still display on the second analog Caller ID telephone, if the caller information is received from the ISDN network before the analog telephone rings.
