for further information.
Exchange Access Code EAC
You may need to enter an exchange access code (e.g. 0) to allow the public exchange to
assign an external line for external calls or for calling back numbers in the calls list.
Entering the EAC
Procedure:
1. Press the softkey under MENU . Scroll to PBX , ACCESS CODE in the SETTINGS menu
and press OK to confirm.
2. Enter the exchange access code.
Note • After having programmed an exchange access code you do not have to
enter it again in a directory entry. However, if you dial off-hook or in call
preparation you still have to enter the exchange access code manually.
• To give the exchange sufficient time to assign a public line, you may need
to program a “pause” after the exchange access code by pressing and
holding down
.
• For further information, refer to your PBX operating instructions.
