Ports used by Meetio

For Meetio to work on your network there are a few ports that needs to be open in order for the devices to access your calendar and Meetio Admin (the central administration tool):

Meetio Admin:

• Port 443 (TCP) to admin.getmeetio.com

• Port 443 (TCP) to stats-api.getmeetio.com
• NTP (Time)
• Port 123 (UDP) to ntp.lth.se and 2.android.pool.ntp.org or your custom NTP server (Meetio devices can also get NTP-server address from the DNS if you have configured it as an SRV-record).
