Hello.

If you are planning on doing call forwarding via the telephone system, do you require 2 lines for this to happen?

One line for the incoming call and 1 line for the outgoing call on the forwarding? It can't use the same line right?

I believe if you setup the call forwarding with the phone service provider, they will do it on their end and you will only need 1 line.

Is this correct?

Thanks.
