Router Settings for Keypad and SIP Phones

Updated 3 months ago by Justin Maxwell

If you're using a SIP phone behind a firewall or router, you may need to open up ports for it to function properly. Most modern phones and modern routers can accomplish this for you automatically using UPnP or other smart port forwarding configuration. However, larger enterprise firewalls may not do this for you and require manual intervention.

Signaling ports

5060 (UDP/TCP) and 5061 (TLS)

Media ports

10,000 to 20,000 (UDP)
