Hello. I need to use the Cisco 232D FXO port with my 3CX v12.5. I created a generic gateway in the 3CX and configured the SIP parameters in the Cisco and it's register but I can't call - out call go in timeout and in call don't get to the 3CX. How can I solve this problem? Thanks you to everyone. And sorry for my bad english but I'm Italian.
