5.2.9 IP Phone Cannot Transfer a Call
Problem
Other terminals can transfer calls, but the eSpace 6805 cannot transfer a call.
Cause
When you press another LINE key to transfer an ongoing call on the eSpace 6805, the account
that is displayed is not the account carrying the ongoing call.
Solution
The correct steps are as follows:
1.
User A sets up a call on a line of an eSpace 6805 with user B.
2.
User A presses any other LINE key on the eSpace 6805. When the account of the
ongoing call is displayed, user A dials the destination number C.
3.
User C hooks off, and users A and C are connected.
4.
User A presses the Transfer key. User B can talk with user C. That is, the call is
transferred successfully.

5.2.10 IP Phone Can Make Outgoing Calls but Cannot Receive
Incoming Calls
Problem
The eSpace 6805 can make outgoing calls but cannot receive incoming calls.
Cause
When the do-not-disturb (DND) function is enabled on the eSpace 6805, the incoming calls
are rejected.
Solution
Check the DND icon. If the icon blinks, you can infer that the DND function is enabled.
