So, I've been trying to do some research on this phone system for a local business and I'm very new to all of this. The phone system is the vodavi Starplus 3514-71. I'd like to connect a cordless handset to the system without having to extend the phone system with more expensive equipment. I've noticed people mentioning connecting cordless sets to the adp on the bottom of the phone, but I can't figure out the details of how this works. I don't yet have a cordless phone to play with and I want to make sure it will be doable before telling the business to spend any money. Can anyone explain the process of connecting a cordless phone to the adp and how to get it to receive incoming calls and make outgoing calls? Also, would the cordless phone need to be made for the vodavi phone system, or would a regular one work?
I apologize, I'm very new to phone systems like this and it's very difficult to find information online anywhere about them. Also, if you could simply link me to any websites with beginner guides to these kinds of phone systems, I'd love to study up and learn more about these kinds of systems. Thank you so much for any help you can provide. Also, I'd be happy to provide any further information if necessary.
