Extension/
Identifier String
MGC Manager User's Guide - VoicePlus Edition
Description
Used with multi-step extension dialing and
participants with PBX or IVR phone extensions. This
field is used to enter the required data for the dialing.
The string listed in the Name field consists of the
following format: (0...9)(Free text)([Ext:
Extension)(p)(extension number)(p)(extension
number)(p)(##]). For example,
9Sales[Ext:p345p222p].
Each section of the string is explained below:
• 0...9 - Any digit between 0 and 9, the digit being
any number that identifies the participant during a
DTMF dial-out sequence. For example, when a
chairperson activates a dial-out session by
pressing *259, *25 is the DTMF command code
that activates the dial-out session and 9 is the
number that identifies a particular participant to
be used in the session.
•
Free text - Optional text field, and may be
omitted.
Note: In conferences where the blast dial-out feature
is activated automatically using the DTMF code *25,
the free text field must start with a digit as shown in
the example: 9Duke[Ext:p345p222p].
•
Brackets [ ] - Brackets indicating a dial string.
Bracket are context sensitive and only this type
of format is to be used.
•
Extension (Ext:, ext:, EXT: are permitted) text
prefix - Code indicating that a string consisting of
a series of digits are to be used during dial-up.
Note: More than one extension number is optional,
certain IVR systems request that you first dial a
department and then extension number.
• p - Induces a pause of 1 second before
transmitting the next digit or DTMF code. There
is no limit to the number of p's in a dial string
Note: When using one second intermissions, it is
important to note that each IVR system has different
content and timing of dialog sequences. Correct
timing for output of DTMF digits might determine
whether a call can be successfully completed.
