Select Line Group for Retries

$retry_linegroup line linegroup

This command allows the specification of a line group to be used for retries of failed transmissions. It causes a $fax_send_line command to be added to the FS file after a failed transmission, replacing any existing $fax_send_line command.

The parameters on this command are used as follows:

line the line number or line group(s) affected, or * for all lines.
linegroup the line number or line group(s) to be used, which must be a valid outbound line for the system but need not be on the same network node that processed the request.

Special syntax is used to force a different line to be used for retries. A line group ending in '~0' is interpreted as indicating exclusion of the line used for the latest attempt. So for example '*,~0' for a fax which failed on line 7 is interpreted as a line group of '*,~7' and line 7 is not used for the next attempt. Each failure appends another exclusion to the string, up to a maximum of one-third of the available outbound lines.

Default: the same line group (or any line, if no group is specified) is used for all transmission attempts.

Example:

$retry_linegroup * Brooktrout ; use Brooktrout board for retries
