I try to route with "alphanumeric" stuff - like 'tetris' in sip://tetris@mytest.example
The DB-Field is an 64 string like route-id. In dr_rules.route-id i can use "named-routes"
if i leave the prefix empty or i fill in only numbers.
With strings i got this error:
ERROR: drouting [dr_load.c:555]: dr_load_routing_info(): failed to add rule id 4 -> skipping
SQL Result for rule-id 4:
# dr_rules
# ruleid, groupid, prefix, timerec, priority, routeid, gwlist, description
'4', '9000', 'tetris', '', '0', 'tetris', '4', 'testroute'
