How to use CT12/CT14

How to Answer a Call:

When the phone rings, press the TALK/FLASH button on the remote. The call should now be answered with the headset.


How to Place a Call on Hold:

Press the TALK/FLASH button on your remote. You should hear an intercom dial tone. Now press END. Your call is now on hold.


Retrieving a Call from Hold:

In order to retrieve a call from hold you generally must go back to your Partner Phone and press the line that is on hold.


How to Transfer a Call with an Announcement:

Press the TALK/FLASH button once. You will hear an intercom dial tone, which means the call is parked. Now, dial the extension to which you want to transfer the call. The phone will ring. When someone answers, announce the call: if he/she accepts the call, press END and the call will be transferred. If no one is available at that extension, press TALK/FLASH and you will be returned to the call.


How to make an Intercom Call:

Press the TALK/FLASH button to get an open line (you cannot place an intercom call while on the line with a caller). You should hear a dial tone. Now press the (*) key and 71. This activates the intercom feature. Now, simply dial the extension of the person you wish to intercom and your voice will be heard through the intercom. Press END when done.

PLEASE NOTE: Intercom feature may not work with the Partner ACS system. Check your phone’s feature guide for other possible ways to use the intercom feature.


How to make a Conference Call:

After you are connected with the first party, press the TALK/FLASH button. This will give you an intercom dial tone, which means the first party is now parked. Press 9 to get an outside line, then dial the new phone number (Note: If you are conferencing someone from an inside line press TALK/FLASH and dial their extension). When the second party answers, press the TALK/FLASH button once. You should now be connected with both parties. In the event that the number is busy, or if there is no answer, press END and you will return to the first party. When you are ready to end the conference call, press TALK/FLASH to hand up on both callers; if you want to continue speaking with the first caller, press END and the last caller will be dropped.
