You can ask the system to forward all your calls to another extension or to an outside telephone number.
When you forward your calls, an inside and outside calls are forwarded to another extension. While your phone is in "call forwarding," you will hear a single ring to remind you that you are using this feature.
You also have the ability to forward your calls in a chain with up to four forwardings. With chaining, call A will forward to phone B, phone B to phone C, and so on. The fourth phone will always ring even if it too is on call forwarding.
And, if you have programmed a distinctive ring for your phone, the extension that receives your forwarded calls will ring your calls with the same distinctive sound.
