I need to make Elastix/Asterisk prevent calling on fax machines.
I've already asked How can we handle outgoing fax calls? and got the main idea, but I don't know the SIP thing well and haven't found a clear step-by-step answer or code with comments, what makes it very hard to understand.
What I understand is that I need to:
- create custom dialplan for Elastix
- route calls to that custom dialplan if AMD is triggered
I got the .conf files including the "amd.conf" one.
How exactly should I modify those files(and which ones) to prevent calling on fax machines(if the answer machine is fax -> hang up)?
Thank you in advance!
