Creating entry in the extensions_custom file

Hi,

I have assigned some extensions the context “ext-local”.
Within this context they can only call local extensions and no outbound routes.
My problem is that when the context is set at “from-internal” the extensions can dial 0 and get the Reception. When the extension is set at “ext-local” they cannot dial 0; They will get a fast busy tone.

I think it has to do with en entry in the extensions_custom file which I have included below. Can somebody help me with the creation of this entry?

[ext-local-custom]

; do here all customizations which are needed for internal only phones like ermergencency calls and so on
