[SR-Users] PerlVDB Usage

Hi All, We are looking to integrate SIPRouter/Kamailio into our existing infrastructure. Currently we have a sip proxy and registrar that handles registration and routing. The main issue we have with integrating SIPRouter/Kamailio into our environment is that the table structure for kamailio's tables are vastly different to our existing database tables. We have several application built around our current database structure so I think it is fair to assume that we will be forced to use the existing structures. I had a look at perlvdb which seems to do what I had in plan, where the table structure is transparent to kamailio. so for example, when a registration request comes in and we then authenticate the user and want to save the location, could we use the perlvdb module to intercept the save and manipulate it so that it inserts/updates/reads data from a table structure that is different to what it is expecting? I've been trying to find an example of how to use perlvdb but have been unsucessfull in my google searches and mailing list searches. Does anyone have an example of how to use the perlvdb module? Thanks Bruce
