[OpenSIPS-Users] Nested reply_routes

[spce at lard.at]

Hi,:

thanks. In my case theres a quite big onreply route, which totally 
works, but is a hassle to read. Therefore I would like to segment some 
stuff into custom "functions", so I can have an easy to understand main 
onreply route and the more complicated logic in special blocks.

A possibility for that would be to call secondary onreply routes from 
the parent route. Is that possible or not?

Liebe Grüße / Kind regards,
Malte
