It's going to be a custom routing module, with our own business logic.
It should load the routes from a database and keep refreshing the data every x interval. For SIP-to-PSTN calls (outgoing to carrier) we need to be able to route based on the callerprefix, customer id (which is added as a custom header), originating IP, and some other fields. I need a way to select the closest matching route, or fallback to the default route, using the fields described above.
Implementing this logic in a stored procedure is quite hard. Another option would be to write a web service and perform http calls to determine the route. I'm just worried that http might delay the setup of calls.
Our routes table contains custom fields, but also fields which are used by the dispatcher module. So once a route is selected, the dispatcher module will use the uri in the route set to rewrite the ruri and possibly do failover.
On first look, I think you really should consider Alex proposal to see if you can get this done with the standard configuration and existing modules. You might want a cron-script that refreshes htables, dispatcher tables or avp's loaded from database, but I fail to see that it can't be done with existing logic.

I'm researching what it takes to create our own custom Kamailio module.
Skilled C programming.
What do you want to accomplish? Are you sure no combination of existing modules and script constructs fit the bill?
Sometimes you really do need a custom module. But I find those cases to be relatively few, at least for applications of Kamailio that are not truly exotic.
