China - Toll Call Loss Plan
Toll pad switching is also provided after call transfer has been completed.
When the toll call is diverted, the diverted party's pad level is switched back
to its original value (unless it is an OPS station using dynamic switching).
The Toll Loss Plan is applied again for the new call as if it is a direct call.
For Call Transfer, it is provided after the transferring party completes the
transfer and drops out. For Call Forward or Hunting, it is provided when the
forwarding or hunting call is answered.
Conference
Conference can be used to transfer calls, eliminating the need for a separate
Call Transfer key/lamp pair on Meridian 1 proprietary telephones. Calls in
the ringing state cannot be transferred with Conference. The third party
must answer before the transfer can be completed.
A conference can also be established after initiating a Call Transfer
operation. After the third party answers, pressing the Conference key
establishes a three-way conference.
When a switchhook flash transfers calls on analog (500/2500 type)
telephones with three-party conference (C6A) Class of Service, the
transferring party goes on hook, leaving the other two parties established.
Telephones with a C6A Class of Service involved in a conference having
more than three parties must add the last party to the conference, then flash
the switchhook and go on hook to complete the transfer.
Dial Intercom
When using Conference or Transfer, the voice option is not provided if the
call is terminated before the conference or transfer is completed. If an
analog (500/2500 type) telephone is part of a Dial Intercom Group (DIG),
the user of the telephone can conference only with another user whose
telephone is within the same Dial Intercom Group (DIG).
Display Calling Party Denied
When a set transfers a call, display information is updated according to the
Class of Service of the respective sets. This occurs for both internal and
ISDN network calls.
If an unsupervised call transfer occurs on an internal call, the DN of the
terminating set is displayed to the calling party regardless of the DPD Class
of Service options that are configured on the terminating set.
Dial Access to Group Calls
Group Call
Call Transfer cannot be applied to Dial Access to Group Calls or Group Call.
