Select Channel Group for Retries
$retry_channelgroup chan group
$retry_linegroup chan group
This command allows the specification of a channel group to be used for retries of failed transmissions. The two command names are synonymous. 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:
| chan | the channel number or channel group(s) affected, or * for all channels. |
| group | the channel number or channel group(s) to be used, which must be a valid outbound channel for the system but need not be on the same network node. |
Special syntax is used to force a different channel to be used for retries. A channel group ending in '~0' is interpreted as indicating exclusion of the channel used for the latest attempt. So for example '*,~0' for a fax which failed on channel 7 is interpreted as a channel group of '*,~7' and channel 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 channels.
Default: the same channel group (or any line, if no group is specified) is used for all transmission attempts.
Example:
$retry_channelgroup * Brooktrout ; use Brooktrout board for retries
