In Japan it's pretty universal for small businesses to have a global speed-dial where every phone in the company has the same list of speed dial numbers. I want to set that up for my client but I'm confused about how to do it. What I finally did was just added the same speed-dial lines to each ephone (using the CLI) which sort-of works, but it has drawbacks:
1. It's a pain to maintain since every time a number changes I have to do it in every ephone.
2. I can only get their phones (504G) to reliably dial the first 12 numbers. Speed dial 13 doesn't work at all and speed dial 14 just dials #1 instead
3. It doesn't work on their SIP conference phone
4. I have heard complaints about how long it takes for AbbrDial to actually start dialing.
So, is there any better way of doing speed dials that can be entered by the keypad (rather than choosing out of a directory) that is the same on every phone across the system?
