domain_name: This table is used by the carrierroute module to provides routing, balancing and blacklisting capabilities. It contains the existing domains, consisting of the ids and corresponding names. More information is available at: http://www.kamailio.org/docs/modules/devel/carrierroute.html

Table 5-1. Table "carrierroute"

name	type	size	default	null	key	extra attributes	description
`id`	`unsigned int`	`10`		no	primary	autoincrement	Name of the column contains the unique identifier of a route.
`carrier`	`unsigned int`	`10`	0	no			This column contains the carrier id.
`domain`	`unsigned int`	`10`	0	no			This column contains the routing domain id. You can define several routing domains to have different routing rules. Maybe you use domain 0 for normal routing and domain 1 if domain 0 failed.
`scan_prefix`	`string`	`64`	''	no			Name of column contains the scan prefixes. Scan prefixes define the matching portion of a phone number, e.g. when we have the scan prefixes 49721 and 49, the called number is 49721913740, it matches 49721, because the longest match is taken. If no prefix matches, the number is not routed. To prevent this, an empty prefix value of "> could be added."
`flags`	`unsigned int`	`11`	0	no			This column contains the flags used for rule matching.
`mask`	`unsigned int`	`11`	0	no			This column contains the mask that is applied to the message flags before rule matching.
`prob`	`float`	`not specified`	0	no			Name of column contains the probability. The probability value is used to distribute the traffic between several gateways. Let's say 70 % of the traffic shall be routed to gateway A, the other 30 % shall be routed to gateway B, we define a rule for gateway A with a prob value of 0.7 and a rule for gateway B with a prob value of 0.3. If all probabilities for a given prefix, tree and domain don't add to 100%, the prefix values will be adjusted according the given prob values. E.g. if three hosts with prob values of 0.5, 0.5 and 0.4 are defined, the resulting probabilities are 35.714, 35.714 and 28.571%. But its better to choose meaningful values in the first place because of clarity.
`strip`	`unsigned int`	`11`	0	no			Name of the column contains the number of digits to be stripped of the userpart of an URI before prepending rewrite_prefix.
`rewrite_host`	`string`	`128`	''	no			Name of column contains the rewrite prefixes. Here you can define a rewrite prefix for the localpart of the SIP URI. An empty field represents a blacklist entry, anything else is put as domain part into the Request URI of the SIP message.
`rewrite_prefix`	`string`	`64`	''	no			Name of column contains the rewrite prefixes. Here you can define a rewrite prefix for the localpart of the SIP URI.
`rewrite_suffix`	`string`	`64`	''	no			Name of column contains the rewrite suffixes. Here you can define a rewrite suffix for the localpart of the SIP URI.
`description`	`string`	`255`	NULL	yes			A comment for the route entry, useful for larger routing tables. The comment is also displayed by the fifo cmd "cr_dump_routes".

`carrier`	`unsigned int`	`10`	0	no			This column contains the carrier id.
`domain`	`unsigned int`	`10`	0	no			This column contains the routing domain id. You can define several routing domains to have different routing rules. Maybe you use domain 0 for normal routing and domain 1 if domain 0 failed.
`scan_prefix`	`string`	`64`	''	no			Name of column contains the the scan prefixes. Scan prexies define the matching portion of a phone number, e.g. we have the scan prefixes 49721 and 49, the called number is 49721913740, it matches 49721, because the longest match is taken. If no prefix matches, the number is not failure routed. To prevent this, an empty prefix value of "> could be added."
`host_name`	`string`	`128`	''	no			Name of the column containing the host name of the last routing destination, using for rules matching.
`reply_code`	`string`	`3`	''	no			This column contains the reply code used for rule matching.
`flags`	`unsigned int`	`11`	0	no			This column contains the flags used for rule matching.
`mask`	`unsigned int`	`11`	0	no			This column contains the mask that is applied to the message flags before rule matching.
