Extension number format
Extensions 1 to 9 are entered as 001 to 009 and extensions 10 to 99 are entered as 010 to 099.
All-call is extension 000.
In 'all-call' mode you can talk to all extensions at once but you cannot hear any extensions.
2. Use the directory– ideal for large systems
Press D on the keypad to enter directory mode and show a list of extension names and numbers.
Press ↑ or ↓ to select the extension you wish to talk to. The selected extension has the symbols > and < on
either side of its name.
If the phone rings when you are in directory mode, press D to see who is calling.
Conference calls
If you are already talking to one extension and another extension calls, you can talk to both at once by
selecting the new call without cancelling the original call.
If you are already talking to one extension and you want to talk to another extension you can talk to both at
once by dialling the new call without cancelling the original call.
There is no limit to the number of extensions that can be involved in a conference call. However, every
extension degrades the audio quality slightly so we recommend that no more than four extensions should
be involved in a conference call.
Errors and omissions excepted. The manufacturer's policy is one of continuous improvement and we
reserve the right to alter product specifications at our discretion and without prior notice.
