I understand.

I think you could use the perlvdb module as a kind of virtual DB module. To quote from the docs:

"The Perl Virtual Database (VDB) provides a virtualization framework for Kamailio's database access. It does not handle a particular database engine itself but lets the user relay database requests to arbitrary Perl functions."

I never used it so far, so i can't give you examples or similar. But you can find probably additional informations about the design and the usage of the module in the (diploma) thesis from the author of this code, especially in the chapters 8-10:

And do you already checked the samples in the module directory at
perlvdb/doc/samples/ ?
