In order for Skype for Business to function properly, the following network ports need to be open OUTBOUND through the network firewall.

 5061 TCP Outbound
 50000-59999 TCP/UDP Outbound

Our IP Addresses are as follows. We would recommend allowing all IP's through your firewall. This will allow your users to utilise local resources if they host meetings closer to a different region.

Global:

185.94.204.0/22**

35.176.92.0 - 35.176.92.15*

2a04:e9c0::/29

North America (California):

13.56.32.160 - 13.56.32.175*

2600:1f1c:353:7600::/56

Asia Pacific (Singapore):

13.228.64.64 - 13.228.64.79*

2406:da18:c3c:cc00::/56

Asia Pacific (Sydney):

103.116.111.0/24
