Replace the handset or press the “C” key in handsfree mode.
This has the same result as a transferring a call between your two
parties, as your extension is now free.
On the other hand, if one of your parties withdraws from the con-
ference call, that will result in the call now being a single call with
the remaining party.
Notes:
If there are more than 2 parties on your telephone, the con-
ference call will be established between the party currently
conversing with you, and the last party who was placed on
hold.
Your extension may also be subject to enquiry calls, refer
back calls, transfers and conference calls initiated by third
party sets.
