4.14 InterChange iQ 2000plus Enhancements
The InterChange iQ 2000plus is distinguishable from the InterChange iQ 2000 by its
additional support of call handling features, intended to supplement the internetworking
capabilities of the PBXs attached. These additional features are briefly described below.
4.14.1 Proxy Diversion
Some Q.931/QSIG PBXs do not support call diversion. InterChange iQ 2000plus can be
configured to attempt the diversion call on behalf of the calling PBX. This is done by clearing
the original (diverted) call and then attempting a new call to the extension to which the call
is to be diverted. However, the success of the procedure depends on whether the DPNSS
network will route the call correctly.
In order for the InterChange iQ 2000plus to perform diversion on behalf of the Q.931/QSIG
PBX, it is forced to break strict compliance with the DPNSS Diversion Service. To minimise
equipment congestion, the proxy diversion re-uses the same outgoing DPNSS channel and
drops the original call before attempting the diverted call.
4.14.2 Redirection Timeout
Operator Redirection applies, in particular, to calls incoming to the DPNSS Operator that
have been transferred to IP ’phones. The application ensures that if the wanted party does
not answer, the Operator is prompted to break in on the call and ask the caller whether
they wish to continue to hold, or try an alternative number. In the case of continuing to
hold, enough information has been provided back to the Operator Station for the call to be
reconnected to the wanted number by a single key push.
This dialogue is only encountered if proxy diversion has been enabled. It is self-explanatory;
InterChange
iQ 2000
can redirect calls transferred by the DPNSS operator
back to the operator if they are not answered.
Do you require InterChange to perform operator redirection?
If you answer
YES
you will have to set a timer value:
We need to know the number of seconds to let a transferred call
ring out before InterChange attempts to redirect it to the operator.
This must be a time long enough to allow the user to answer but
shorter than the ringing cut-off timer in the calling PBX or network.
You may want to consider whether to set the timeout shorter than any
divert-on-no-reply timer that might run at the called PBX.
How long shall InterChange wait before redirecting [5 .. 60 secs] :
Set the timeout, as directed. If you decide not proceed with configuring Operator Redirection
at this point you can either type
UNDO
or set a timeout value of
0
, in which case cancellation
will be confirmed by the comment:
Operator redirection support will not be enabled.
