Possible values
A character string
Explanation
Specifies the code that the switch uses to identify this channel when it
transmits information via the exchange data link about the call that is in
process on this channel.
The length of the character string must be equal to the length specified
by the Line Identifier Number Length parameter in the Exchange Data Link parameters
group.
The formats of the line identifiers are different for the various exchange
data links:
- ACL
- The line identifier is an ASCII character, usually Q for an analog tie
trunk, followed by five hexadecimal numbers in the format TTLLL where TT are two hexadecimal digits that specify the trunk group, usually
in the range 01 to FF; and LLL are three hexadecimal digits that
specify the line number within a trunk group, usually in the range 001 to
FFF.
- SMDI or SMSI
- The line identifier is made up of seven digits in the format gggnnnn, where ggg is a three-digit number that specifies the message
desk number (also referred to as the line group), usually in the range 001
to 999; and nnnn is a four digit-number that specifies the message
desk terminal (also referred to as the line number), usually in the range
0001 to 2047.
- VMS
- The line identifier is a number between two and five digits in length.
For a specific implementation, the number of digits is fixed (that is, all
lines from a switch have the same number of digits).
- CallPath
- The line identifier is the physical phone number for the channel. CallPath refers
to this as the Party number.
Each line identifier that is configured in the Blueworx Voice Response system must be unique
and must be configured on the correct channel. Otherwise call information
might be sent to the wrong channel, resulting in the call information either
being sent to the wrong incoming call, or being lost.
You might have to ask your service provider to give details of all the
line identifiers that have been set up on your switch. The numbers do not
always follow a logical sequence from one channel to the next, so it is not
safe to assume that the identifiers just increment from the first one.
