Hi, With this LCR release from Kamailio 3.1 the table 'lcr_gw' makes four fields unique: lcr_id, ip_addr, port and hostname. This table is also responsible for setting 'strip' and 'tag' parameters values for the gateways. What I am trying to accomplish is to use different strip and tag values for the SAME gateway based only on what was dialed by the user. In 1.5 LCR for example, if user dialed 444 or 555 and both prefix belongs to the same gateway, I could use gw-sip for 444 (with values strip 1 and prefix 22) and also gw-sip for 555 (with values strip 2 and prefix 33). While this duplicate data, it was possible to play with routes without touching the config file. I am looking for ideas on how to implement that on K3.1 without using ifs, strip and prefix tied (statically) in the script file. As far as I know, for every new lcr_id inserted, I will need a corresponding load_gws(new_lcr_id) in the script. Regards, Alexandre.
