I have a Sonicwall TZ190 and just purchased IP phones from 8x8. When I connect the phones to my network, i get a message that says "Not connected". The folks at 8x8 said that I need to adjust my firewall settings to enable QoS and to disable SPI. They also provided this link: http://www.8x8.com/Support/BusinessSupport/Documentation/QoSSettings.aspx
I'm a novice when it comes to the sonicwall and am looking for detailed steps as to how to configure my router to play nicely with my IP phones. If you need any additional information from me, please let me know. Thanks in advance for your help!
