Router Settings for Keypad and SIP Phones

Updated 5 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.

This information is intended only for system administrators. As mentioned in our "Sanity Check," we do not provide technical support for SIP phones.
