Hello,
we’re currently looking to build a dial plan that would compare the DID of an inbound caller against database such as MSSQL or MySQL to provide whitelist functionality for a paid service route. With this in mind we’re having a hard time finding development documentation that goes over the context in where dial plans execute and what language it’s based on.
I was hoping someone could provide some high-level pointers of what we’re getting into, along with maybe some basic dial plan development information you may have access to.
Any help would be greatly appreciated!
