Additional ISDN features
The following ISDN features are supported by IP Office 4.0 and later on both PRI and BRI trunks. Note that
availability of these features is dependent on availability and support from the ISDN service provider, for which
there may be charges.
· Malicious Call Identification – MCID
(24xx, 46xx, 54xx, 56xx, 9500, 9600, T3, T3 IP, DECT telephones)
Short codes and button programming features are available so that users can trigger this activity at the
ISDN exchange when required. This feature is NOT available on standard ISDN DSS1 telephones.
· Advice of Charge – AOC
(T3 digital and IP telephones only; Phone Manager)
Advice of charge during a call (AOC-D) and at the end of a call (AOC-E) is supported for outgoing ISDN
calls other than QSIG. The call cost is displayable on T3 telephones for call accounting purposes. The IP
Office allows configuration of call cost currency and a call cost mark-up for each user.
· Call Completion to Busy Subscriber – CCBS
(2400, 4600, 5400, 5600, T3, T3 IP, 9500, 9600, DECT telephones; Phone Manager)
CCBS can be used where provided by the ISDN service provider. It allows a callback to be set on external
ISDN calls that return busy. It can also be used by incoming ISDN calls to a busy user. This feature is
NOT available on standard ISDN DSS1 telephones.
· Partial Rerouting – PR
(2400, 4600, 5400, 5600, T3, T3 IP, 9500, 9600, DECT telephones; Phone Manager)
When forwarding a call on an ISDN channel to an external number using another ISDN channel, partial
rerouting informs the ISDN exchange to perform the forward, thus freeing the channels to the IP Office.
This feature is NOT available on standard ISDN DSS1 telephones and it is NOT supported on QSIG.
· Explicit Call Transfer – ECT
(The normal usage of this feature is by a third party application)
ECT is supported on the S0 interface. A Call to an S0 Endpoint can be transferred to any other device
such as an analog, digital or IP endpoint or to any trunk. The normal usage of this feature is by a third
party application connected via one or more S0 interfaces to IP Office. One example is the VoiceDirector,
an automatic call assistant.
