Hi, I have a problem currently where I cannot talk because of the University Internet. I have tried contacting my University about this too, but they cannot do anything about it.
They have told me to contact the support services for these games for advice, so I’m just posting here to see if there’s any way around this issue.
If anyone can help me in any way, I’d be very appreciative.
Hi DPickle
The issue you are having may be related to internet restrictions that exist in business type connections like the ones most universities have so I would try using a different internet connection to see if the issue persists or not.
If it still occurs after changing the connection, then I would advise that you try this guide that usually solves most voice chat problems. 
Hi, Sadly I don’t think I can use a different connection. The only one provided by my University Accommodation is linked with the University and doesn’t allow me to change any Internet/Router settings.
Thanks for your help, I was just wondering if there were any other ways to get around this. I believe there are also others at the University having the same problem.
Unfortunately there generally isn’t really a way to get around network-level restrictions, outside not using said network or effectively bypassing the device of the network (usually a firewall) that imposes said restrictions (e.g., via a VPN-tunnel).
That said: it is almost certainly possible for the network administrator to enable access to VoIP-functions (which the Overwatch-voicechat is based on) within the network. If they want to do that is an entirely different kettle of fish, but if you have a good understanding with the admin team: it’d certainly not hurt to share this link and also this official listing of our network/peering setup with them.
The details in the links cover all network ports and services that will be used for our games and their related voicechats, which should give them all they need to enable these functions if so desired.
