[Serusers] lcr module error - no prefix column and no avp visible

Hi, During the lcr module set up I encountered the following problems: a) there is no prefix column in the gw table so when the modules is initialized it returns an error b) the ip_addr column in gw table is an int(1o) type how should I specify it to get the IP like 192.168.0.74? c) when I invoke the load_gw() there is the debug info that gw_uri_avp was created but when I then try to print it I get that avp not found, what is wrong? log below: Oct 31 11:38:24 sen ser[12273]: load_gws(): DEBUG: Added gw_uri_avp < sip:touk1@138.64.116.11:5070> Oct 31 11:38:24 sen ser[12273]: AVP '$gw_uri_avp' not found Waiting for Your feedback Regards Tomasz
