Hello, the transalation records are cached by kamailio and precompiled, so there are optimizations to increase the speed of processing. But have in mind that the rules are matched one by one from the same dpid, in the order of priority. For the records where you don't have substitutions/replacement, you can set empty string -- it should work.

I'm expecting have lot of dial-plan entries, some of them with manipulations, others without. Anyone can see here any limitation on this implementation? One thing that I have noticed is that dial-plan module enforces me to fill the fields substr_exp and repl_exp even if i don't have any manipulations to apply. I'm also concerning about performance issues with lot of dialplan entries. What are your thoughts about this solution?

Hello, the matching rules are stored pre-compiled in memory, not being parsed every time, unless you have rules with variables. Combining mtree with dialplan can increase performances, just be aware that if you have non-numeric values stored in 'tprefix' column, it is going to use a lot of memory for lot of records.

I have thought in another solution that is use diaplan module only for apply manipulations and use mtree to match prefixes after apply manipulations. What is your opinion on this? Thank you again for your great support.
