Hi Daniel, I need to access custom database tables (i.e. not default with kamailio) from a lua script (extending kamailio.cfg).
Processing any incoming SIP request starts with a lua function and that in turn call other functions - and each one needs database access for taking routing decision. This seems to be a huge performance issue (connecting/querying db in several functions for a sip invite). Could you please suggest - Any global scope (loads only once during start-up, but valid for each routing) in kamailio, where the required tables could be cached. - Or any other way to address this. Thanks in advance.
