Additional network requirements for companies moving from on premise Skype

Occasional Contributor

One of our clients is migrating from on premises to O365 and moving from Skype for Business on premises to Microsoft Teams. They would like to know if there are any additional network requirements for the audio / video conferencing compared to the on premise Skype installation.

I don’t know them by heart by I guess ports and such differ! Read up here: https://docs.microsoft.com/en-us/microsoftteams/prepare-network

Requirements are different.

Teams requires fewer ports than SFB on-prem does for external access, but it requires some ports that are not listed for SFB to be opened towards O365 IP ranges, and that needs to be maintained operationally.

Also, it needs internet connections to O365 to be designed and sized properly, since all traffic goes there.
