Hi sorry
Was abit vague. It will be for a small business with 5 extensions.
The features would be Auto Attendants, Call Back, Automatic Daylight Saving Time Adjustment, Call Hold,Call Park,Call Pick-Up, Caller Display, Do Not Disturb, Ease of Installation and Configuration, Line Hunt Groups, Music on Hold, Remote Extensions & Management, Voicemail and Caller Line Indentity to name but afew.
We are currently using Blueface and will keep using them but we are having alot of problems with our broadband provider so were looking to go the ISDN FRA route. The PBX systems should serve our PSTN needs and voip.
Hope this helps
