so i been trying to FaceTime with my friend. she is at work with wifi & i myself am i work with wifi...when we try it says connecting & then fails (this is when i dial out) then when she dials out nothing comes thru my phone. also happened with another friend where it says connecting then it fails. is it because i'm at work & it might be firewalls (i work at a hospital/university) so maybe its that not sure....

    Make sure you are able to receive a voice call prior to using WiFi. FaceTime does require an initial voice call for a minute then you can use FaceTime.

    Secondly, it may be blocked by your work sites. FaceTime requires specific ports for port forwarding: 53, 80, 443, 4080, 5223, and 16393-16472 (UDP). If your work site blocks most of these ports and ranges, there's no connectivity.

    Also IT management has the right to block FaceTime due to security reasons and bandwidth. FaceTime requires a great deal of bandwidth and their ISP has as much limits as your house connection. Businesses may have a higher bandwidth cap but they have to watch their limits in costs like your house bandwidth caps.
