What ports does Ooma VoIP actually use ?

Tags: , ,
It is sometimes useful to setup QoS in your router, and if the Ooma Telo/Hub device is behind it you may want to prioritize traffic to it. Below is a list of the ports used by Ooma for data and voice traffic:

UDP 1194 -- Ooma sets a VPN tunnel on this port used for call setup/control (should use highest QoS priority)
UDP 49000-50000 -- actual data, VoIP call payload

Other ports used:
UDP 3480
UDP 514
TCP 443

Notes: All those are outbound ports, outbound QoS is usually more important as there is less available upstream bandwidth on residential connections. You can use the same inbound ports to the Ooma device if need be.
