Internally on either phone you were able to HF communicate. With that being said it did depend on the programming of the station parameters. you could have it come over two way HF or have the called sets mic turned off making a person either press the mic key or pickup the handset.
I'm not sure of the programs needed but PM me if you need help on this.

Easiest way to upgrade a customer is to make them happy...if its working for them just bid your time till they need you.
