Apologies if this has been asked before - forum search didn't turn anything up.
I'm trying to design a specific call flow for incoming calls to a user and cannot seem to crack it.
1 - Ring IP phone and iOS apps simultaneously.
2 - If no answer, call mobile number - cannot use "Ring my mobile...
Good idea!
I created a fake trunk pointing to 127.0.01 - registration definitely failed - but it doesn't work unfortunately, call is still routed to the extension.
None of the other threads received answers from anyone at 3CX - could anyone tell us if this is possible?
Hello,
It seems as though my question has been asked a number of times and that no one has ever found a real solution (or I couldn't find it!) - searching the forums has returned the following threads:
Blocking Extension to Extension calls
Prevent users groups calling other user groups...
I'll definitely be using a firewall - I was just wondering if any part of of 3CX relies on iptables as part of it's built-in security measures?
Just looking for confirmation :)
If not I'll go ahead and disable iptables completely.
For v15.5 on debian does 3CX require iptables at all or can disable it completely?
Are iptables used to block malicious user agents, too many username/password and client registration attempts or is that handled through a different mechanism?
