Disable SIP ALG or Bridge to Supported Router
To use this router you will need to login to the web interface for the router and disable the ‘SIP ALG’ setting on it. If this option is not available you can try setting it to bridged then connect it to a compatible router so that the 2wire router acts as a simple modem rather than a router. If bridging is not possible either, you must replace this device as it will prevent you from using VOIP services.
