[Asterisk-Users] Business telephones

[Martin]

Hello.

I'm looking for some guidance from people that either have/use or install 
asterisk business systems.

What is the best, mid-range multi-line and extension business type SIP 
hardphone, with all the important options functional.

I'm looking for something that can do this (or most of it):-

1)	Full duplex
2)	2-line, 16 character (or similar) display
3)	about 4 line keys or keys that can be programmed as line keys
4)	12 extension keys or keys that can be programmed as extension keys
5)	Mute key
6)	Ringer volume key
7)	Handset volume key
8)	Speaker volume control
9)	Buttons that light (green when you are using the line), red someone else 
using the line
10)	TRAN (transfer)
11)	FEAT (Feature - send code) - used when exceed the number or programmed 
buttons
12)	HOLD/DND


Some of the asterisk features I am looking for (I'll try and expand this later 
and probably add to wiki):-

g)	Direct inward line - ext line ring assigned extensions with selectable ring 
tones
h)	External paging - one or multiple zones
