SQLOPS would work. The difficulty is in writing your rules in your query. Implementing the query and getting results in Kamailio is trivial if that’s done. If your rules are strictly based on matching prefixes (which is pretty common in telephony) and you’re using postgres, the prefix opclass is pretty helpful in making the queries more efficient:

Hi,

I'd like to build an LCR solution that routes on both CLI & destination e.g.

CLI matches ^\+49*, destinations matches ^\+44* => route to gateway 5

for a large rule set (~ tens of thousands). Any recommendations for which modules to use? Can kamailio perform this particular task well or should I look at another solution? I'd be very grateful to hear about any experience of doing this. Many Thanks.

Regards,

John
