274 Call Transfer

Operating parameters

A separate Call Transfer key/lamp pair must be assigned to Meridian 1

proprietary telephones.

A transfer allowed Class of Service must be speciﬁed for analog (500/2500

type) telephones to access this feature.

If trunks are involved, successful completion of a transfer depends on the

access limitations assigned to the stations and trunks.

While the originating side of a call is linked to a transfer or conference key

(that is, the originator of a transfer/conference call has not yet completed

the transfer/conference), the terminating side cannot initiate a transfer or

conference. Conference calls cannot be transferred.

Feature interactions

Advice of Charge for EuroISDN

When a set is connected to an ISDN CO trunk conveying AOC charging

information, the received call charging information is stored against this set.

If the user transfers the call while the dialed set is still ringing, call charging

information is stored against the transferring set until the call is either

answered or abandoned by the external party. If the user consults with the

dialed transfer set, charging information is stored against the transferring

set until the call is either answered or abandoned. If the transferred call

is redirected by a call redirection feature, the call is charged against the

transferring set until the call transfer is completed and the call is answered.

In all instances, if the call is answered, new call charging information is

stored against the set receiving the transferred call.

AC15 Recall: Transfer from Norstar

A party involved in a consultation call (an active or held party) cannot initiate

a consultation call for preventing call chaining. This principle is maintained

in the following cases:

•

the party is an AC15 trunk (if it attempts to initiate a consultation call,

the recall signal is ignored), and

•

the party is a local set, but the consultation call is made by an AC15

trunk.

Attendant Break-In

Until a transferred call is connected, the attendant cannot break in to a

call that is being transferred.
