I created my own custom IVR using PAGI and put the extension in extensions_custom.conf. Everything is working and I didn’t encounter any problem if the call is internal of Asterisk. However if the call is coming from an external call (example via Avaya) it is not visible. I just received a busy tone.
I made a modification on the extensions_additional.conf and modified some existing IVR there to point to the custom IVR that I made. It’s working but unfortunately it will be updated by Asterisk Admin, thus I’ll lost my modifications.
How can I put it in the extensions_custom.conf while making it accessible externally. I hope you can help me with this.
