I don't see any for sale, but is there a way to get one hooked up to it? Basically, I need 15+ speed dials. Something like this would be great, but for the Polycom instead of Grandstream: ...
Basically I would like speed dial on this so I can press 1 and it will dial 101 AND I can press 2 and it will dial 555-555-5555. Is there a way to do this?
