[SR-Users] cr default route

Hello, The documentation of carrierroute says "If flags and mask are not zero, and no match to the message flags is possible, no routing will be done." Then is there any route entry which can act as default gw (like an always-match entry)? For example this 'carrierroute' table: +---------+--------+-------------+-------+------+------+ | carrier | domain | scan_prefix | flags | mask | +---------+--------+-------------+-------+------+------+ 1 | 1 | 1 | 156 | 500 | 0 | 2 | 1 | 1 | | 0 | 0 | 3 | 1 | 2 | | 0 | 0 | +---------+--------+-------------+-------+------+- Here if ruri is 156xx, and there is no flag set, then the cr module does not find a match because of the non-zero value in the flag column (entry 1). But I want to route this call via carrier1 domain1 and scan_prefix empty-value entry (entry 2). How can I set a default route entry here? Is possible with cr? Now I only find it possible via a pstn.def_gw_ip variable. Thank you, Claudio
