Hello there,
I'm evaluating if I can use dial-plan and dispatcher module to build a kamailio routing server to route calls based on number dialed(sometimes the number dialed can be Alphanumeric).
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?

Thank you
