If skype works but Viber does not, it is likely blocked by your company's firewall.

Viber specifically uses several high level ports (TCP 5242+4244, and UDP 5243+9785). If your company's guest wifi network is blocking these ports, you won't be able to connect with Viber. It would be pretty reasonable, for a guest wifi which is intended to be used only for web browsing to block everything except port 80/443.

Skype uses port 443 for a lot of it's communication which is why it still works on the guest wifi network.

Basically, this is something you have to take up with your company's IT department.
