Problem w/Obi 100 & DD-WRT router

Banging my head against the wall on this one.  I have Verizon DSL and a Westell 7500 DSL Modem/router.  When I'm using the Obi 100 (with Google Voice) plugged into the 7500 all works great.  Call quality excellent, etc.  I changed my setup and put the Verizon Westell 7500 into bridged mode and connected a Linksys WRT54G V2 router running DD-WRT dd-wrt.v24-13064_VINT_std.bin  Everything on my network functions great except the Obi.  Once the Obi is hooked into the router call quality is very bad with every other word getting chopped off and many instances of "no service is available".  So far I've tried giving priority in DD-WRT to the mac address of the Obi, I've even DMZ'd the Obi, all without success.  Rebooted everything many times, still no luck.  The odd thing is when I make a call with Google Voice from any of my computers the sound quality is great.  No drops, no cutouts, all just works as it should.  Streaming Audio and Video all show good.  Latency across the board is good.  Speed Tests show me getting very close to my 7MB/768 provisioned speed.  I even tried a second router with DD-WRT (a belkin) and got the same results.  When I take the DD-WRT router out of them mix, turn off bridging in the Westell mode/router the Obi sound quality is once again up to par.  Anyone know if there are any settings in the Obi device itself that can be tweaked to resolve the issue.

RonR:
You might consider flashing your Linksys WRT54G V2 router with Tomato v1.28 to see if you experience any problems.  That's what I use in a WRT54G V2 router here with excellent results.

My guess is that it has something to do with the bridging.  I have been using dd-wrt (DD-WRT v24-sp2 (10/26/10) big) fine with comcast since I got the obi.  You could also try newer firmware version or tomato like RonR suggested.  If neither work, it is probably the bridged mode.

RonR are you using DSL w/PPPOe?

Yes.

Netopia 2241N-VGx DSL Modem running in Bridged Mode to the WRT54G doing the PPPoE from Tomato.

I also have a PAP2 running alongside the OBi with no problems.

Bridged Mode shouldn't be an issue.  In fact, without the modem being in Bridged Mode, you're looking at a double NAT situation which is more likely to be problematic.
