Specify Fax Line to be Used (Transmit)

$fax_send_line line [channelrange]

This command specifies that a particular outgoing line or line group is to be used for this call.

For a fax-on-demand callback, CopiaFacts generates this command in the FS file if the Y option is used on the $callback configuration command to force transmitted to be made on the same line as the request. Otherwise, and in a user-generated or broadcast FS file, this command overrides any $fax_send_line command in the user profile.

Warning: using $fax_send_line commands very often results in severe performance degradation.  This is because FS files are picked up for processing even if the specified lines are busy, and then have to be discarded.  The result is an under-utilization of outbound resources.  If possible use different TOSEND queues, not $fax_send_line to specify special processing, and enable the queues on specific COPIAFACTS instances.

The parameters on this command are used as follows:

line the line number or line group(s) to be used, which must specify a valid outbound line for the system but need not be on the same network node that processed the request.
channelrange a single range of telephony channel numbers to indicate the telephony board to be used for the outbound call. Currently this parameter applies to Dialogic primary-rate telephony connections only.

Variables expanded from the line parameter must either be system variables or must be control variables defined in the FS file. User profile variables are not available at the time the send line is determined. Variables on this command are expanded each time the FS file is processed, not (as with other FS commands) when the FS file is first loaded.

Default: any line configured for outbound may be used.
