I have a requirement of connecting existing PBX with the Asterisk. We are doing this first time integration.
We have legacy PBX system with the analog PSTN line.
Can anyone tell what are all hardware/software we need if we plan to run the asterisk on the server.
Asterisk will be running on the Centos linux with the Dell server as its hardware
Basically if someone calls the specific number configured on the PBX the call should be routed to the Asterisk for IVR.
