Hi there! My name is***** would be my pleasure to assist you with this. I have attached a link to the complete user manual for you. It is in pdf format and can be saved to your computer for later viewing or printed out.
I can find no reference to a call forwarding feature in the manual. However, it is very likely that the call forwarding feature is offered by your phone service provider. If you will tell me who your provider is, I will find instructions for you.
