Apple has released guidance aimed at enterprises looking to use the iPhone 4 for internal video calls.
The company recommends that enterprises open up a number of their network ports in order to take advantage of the phone's FaceTime feature.
"Internet traffic moves through a firewall based on service-identification numbers that are referred to as ports. Certain ports must be open for FaceTime to work," the firm said.
"Network administrators typically open a minimal set of network ports, allowing the traffic for approved applications to enter and leave the network while blocking other network traffic."
It added that to make FaceTime video calls over a Wi-Fi network, firms will have to enable port-forwarding on ports 53, 80, 443, 4080, 5223, and 16393-16472 (UDP).
V3.co.uk has been trialling FaceTime in the office and so far the results have been reasonable – the sound and video quality is good but there is some jitter.
FaceTime services are currently limited to Wi-Fi networks.
