[Freeswitch-users] IVR Architecture

[João Mesquita]

In my opinion, the language you are using pretty much depends on the project requirements. C will always be faster then anything else if implemented correctly. Also, there is advantages of using native APIs (no matter with ESL or as a module).

Nonetheless, the implementation is more complex, requires more knowledge and at last and most important, TIME. Do you have the time and resources to do it in C and will it be justified based on the project budget you have?

Other then that, I would use ESL because you get the benefit of having your application running on another box and even have it control several boxes at once which is a common requirement for large IVRs.

I hope it helps.

Regards,
