50808?? That is connecting the CCR server to the IP Office.
To just login to CCR (which it sounds what is required), then you need access to the web side of the CCR server. Same as on site.
Port 80 to the CCR server. An 'IT Manager' should have been able to work out how to access a web page surely!!!!
DON'T DO IT!!! Take Peters advice and tell him it;s unsecure and needs a VPN connection to get at it.
If he asks if he can change the port from port 80 to something none standard to try hide it from hackers, put the phone down on him and never go back.
