Nested realms and inheritance

Hi community

 

I'm trying to route calls based on origin (From) through different realms to have different behaviour for early-media.

I have set up a parent-realm and a child-realm like this:

 

identifier realm1
early-media-allow none

 :

 

identifier realm2
parent-realm realm1
early-media-allow ()

  :

 

And of course a LP to match either realm1 or realm2, based on From-address.

 

The question is, will realm2 inherit early-media-allow from realm1 or will it be undefined?
The goal is that call routed through realm1 will not be allowed early media, and call routed through realm2 will be allowed.

 

Thanks in advance.
