Best WRT router for VoIP QoS

    I've always found this forum to be a great source of information, so I have a question.

    Which WRT-type router is the best for VoIP QoS.

    I have a VoIP server running Asterisk PBX and right now it is simply plugged into a business T1 line, which it shares with around 50 desktops. As you can imagine this wreaks havoc with my VoIP bandwidth.

    So in order to change this situation we are getting a dedicated fiber-based connection, 10 mbit up and down. I do want to leave this connection open for limited wireless use and the occaisonal download.

    My idea is this. Connect a WRT 54GL to the broadband connection, then connect the VoIP server to the WRT and setup QoS. Where things get fuzy for me is whether this is the best solution. Also whether or not this will work with the two static IP's that I will have on this broadband line.

    So my question again is; which WRT based router and which 3rd party firmware would be best.

    Thanks in advance

    probably the best is dd-wrt firmware (v23 SP1) has it has a stronger QoS than other firmware parties.

    I presumed these two static IP #s are public IP addresses assigned to you from your ISP. If that is the case, you will first need an intelligent switch with QoS to connect to your ISP to fasilitate these two IP addresses, i.e. one for each router. Without this switch, you will still be having the same problem.

    For the WRT54 router, I have run a Linsksys WRT54GS v3 with DD-WRT v23 + VoIP (SIPatH) package since 12/26/2006 (almost five months). IIRC, I only had to factory reset the router twice. I have configured the router with QoS for VoIP priority. I did not notice any jitters talking through any VoIP lines with friends across the continents while heavily downloading Linux kernels and/or any ISO files of the size of about 5GB @ a full throttle. While this happened, I managed to transfer ISO files between computers behind the router through FTP with an average speed of 9.2MBps ~= 75Mbps.
