I have just pushed a more generic way to allow remapping log levels for local purpose of the module when using LLM_XYZ() log macros instead of LM_XYZ() and updated the pdb module to offer a modparam for INFO level to be remapped. The most relevant commit:
- https://github.com/kamailio/kamailio/commit/03203d1baa5f185db8743a90f889e548... - https://github.com/kamailio/kamailio/commit/e818baa1b21249529c93990ef0340dd8...
To get the equivalent of what you wanted to change, set ll_info modparam to 3.
If there are problems, open a bug in the issue tracker.
