You could use LCR after getting the $var(group) and use that value as LCR 
"from_user" field (lcr table) in order to select the gateways in order of 
preference. This is: configure in LCR some gateways (failover and redundancy 
based on LCR priority and weigh) for each $var(group) value, which would match 
the "from_user" field.
