Hi, I'm trying to use LCR with kamailio v5.5.4 gw, rule and rule_target are stored on mysql. for lcr rules, do you know if prefix is mandatory ? I first wanted to start using request_uri instead and leave the prefix column null/empty because prefix seems not to support regexp, I don't want to add the same rule with different prefixes. but I'm facing issues my database is fulfilled with : lcr_gw +----+--------+--------------+---------------+----------+------+--------+------------+-----------+-------+--------+-------------+-------+---------+ | id | lcr_id | gw_name | ip_addr | hostname | port | params | uri_scheme | transport | strip | prefix | tag | flags | defunct | +----+--------+--------------+---------------+----------+------+--------+------------+-----------+-------+--------+-------------+-------+---------+ | 1 | 1 | carrier1 | 10.78.51.3 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | fd=carrier1 | 0 | NULL | | 2 | 1 | carrier2 | 10.78.51.3 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | fd=carrier2 | 0 | NULL | | 3 | 1 | carrier3 | 10.192.50.212 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 6 | 1 | carrier4 | 10.192.50.3 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | fd=carrier4 | 0 | NULL | | 10 | 1 | carrier5 | 10.192.50.3 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | fd=carrier5 | 0 | NULL | | 18 | 1 | carrier6 | 10.192.50.214 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 20 | 1 | carrier7 | 10.192.50.210 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 30 | 1 | carrier8 | 10.192.50.211 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 31 | 1 | carrier9 | 10.192.50.216 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 32 | 2 | media1 | 10.192.50.232 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 33 | 2 | media2 | 10.192.50.233 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 34 | 2 | media3 | 10.192.50.234 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 35 | 2 | media4 | 10.192.50.235 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 36 | 2 | media5 | 10.192.50.240 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 37 | 2 | media6 | 10.192.50.241 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 38 | 2 | media7 | 10.192.50.242 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | NULL | 0 | NULL | | 39 | 3 | xivo-231 | 10.192.50.231 | NULL | 5060 | NULL | NULL | 1 | NULL | NULL | cps=5;cc=50 | 0 | NULL | +----+--------+--------------+---------------+----------+------+--------+------------+-----------+-------+--------+-------------+-------+---------+ lcr_rule +----+------------------------+-----------------------------------+------------------+--------+----------+-----------+---------+---------+ | id | desc | request_uri | lcr_id | prefix | from_uri | mt_tvalue | stopper | enabled | +----+------------------------+-----------------------------------+------------------+--------+----------+-----------+---------+---------+ | 1 | Default | .+ | 1 | NULL | NULL | NULL | 0 | 1 | | 2 | France GSM | (0|(|00|\+)33)[67]\d{8} | 1 | NULL | NULL | NULL | 1 | 1 | | 3 | France | (0|(|00|\+)33)[1-59]\d{8} | 1 | NULL | NULL | NULL | 1 | 1 | | 4 | International default | (00|\+)[1-9].+ | 1 | NULL | NULL | NULL | 1 | 1 | | 5 | Italy | (00|\+)39.+ | 1 | NULL | NULL | NULL | 1 | 1 | | 14 | to_oldmedias | .+ | 2 | NULL | NULL | NULL | 0 | 1 | +----+------------------------+-----------------------------------+-------------------+--------+----------+-----------+---------+---------+ lcr_rule_target +----+--------+---------+-------+----------+--------+ | id | lcr_id | rule_id | gw_id | priority | weight | +----+--------+---------+-------+----------+--------+ | 25 | 1 | 3 | 3 | 1 | 1 | | 26 | 1 | 3 | 18 | 2 | 1 | | 28 | 1 | 3 | 30 | 3 | 1 | | 29 | 1 | 2 | 30 | 4 | 1 | | 30 | 1 | 2 | 3 | 2 | 1 | | 31 | 1 | 2 | 18 | 3 | 1 | | 32 | 1 | 2 | 20 | 1 | 1 | | 33 | 1 | 1 | 30 | 1 | 1 | | 34 | 1 | 12 | 1 | 1 | 1 | | 35 | 1 | 12 | 10 | 1 | 1 | | 37 | 2 | 14 | 32 | 1 | 1 | | 38 | 2 | 14 | 33 | 1 | 1 | | 39 | 2 | 14 | 34 | 1 | 1 | | 40 | 2 | 14 | 35 | 1 | 1 | | 41 | 2 | 14 | 36 | 1 | 1 | | 42 | 2 | 14 | 37 | 1 | 1 | | 43 | 2 | 14 | 38 | 1 | 1 | | 45 | 1 | 2 | 10 | 3 | 1 | +----+--------+---------+-------+----------+--------+ to test gws, I use kamcmd for example : kamcmd lcr.load_gws 1 s:0600000001 s:02111111111 s:0600000001 arg 1 : prefix or $rU arg 2 : from_uri arg 3 : request_uri result is OK with 5 gateways selected but in real test situation with the following config file : kamailio.cfg : request_route { ... if(!load_gws(1,$rU,$fU)) { sl_send_reply("500", "Cannot load gateways");
