Problem

4.2.10 IP Phone Can Make Outgoing Calls but Cannot Receive
Incoming Calls
Problem
The eSpace 6870 can make outgoing calls but cannot receive incoming calls.
Cause
When the do-not-disturb (DND) function is enabled on the eSpace 6870, the incoming calls
are rejected.
Solution
Check the DND icon. If the icon blinks, you can infer that the DND function is enabled.
When the eSpace 6870 is not used, press DND to disable the DND function.
Issue 01 (2012-06-20)
When the IP phone supports G.711 A-law/μ-law codec, it is recommended that you set the highest
priority for G.711 A-law/μ-law, that is, set choice 1 in the Preferred Vocoder area to G.711
A-law/μ-law.
User A sets up a call on a line of an eSpace 6870 with user B.
User A presses any other LINE key on the eSpace 6870. When the account of the
ongoing call is displayed, user A dials the destination number C.
User C hooks off, and users A and C are connected.
User A presses the Transfer key. User B can talk with user C. That is, the call is
transferred successfully.
