I am using an ObiHai 110 and Google Voice on a LinkSys WRT54GL router with the latest Tomato Firmware Version 1.28. I am trying to improve the quality of my VoIP calls using the QOS in Tomato but can't seem to get an improvement. The MAC address of the ObiHai box is 9C:AD:EF:00:49:C1 The IP address is 192.168.1.112. In Tomato QOS Classification screen I added two classifications for VoIP as the only two Highest Class categories (I first tried with the MAC address entry but as that did not help added the IP address one): 1) From Src MAC of 9C:AD:EF:00:49:C1, Any Port and Protocol 2) From Src IP 192.168.1.112, Any Port and Protocol But then tried doing a large upload and download with a VoIP call to my landline and on the outbound side get severe drop out. When looking at the QOS View Details screen I still see entries for the VoIP box as having the lowest classification: UDP 192.168.1.112 10000 c-24-6-168-77.hsd1.ca.comcast.net (18.104.22.168) 11100 Lowest UDP 192.168.1.112 53292 pw-in-f126.1e100.net (22.214.171.124) 19295 Lowest I rebooted the router after making the changes and am utterly confused by this! Any help would be greatly appreciated.
