Can't talk to cell phones with 202
Shale:
1) Yes. The LAN should be able to go at whatever your router can do, since it is not going thru the OBi.
2) I don't know what to expect. Your 67% drop surprises me, but I have not seen any such data previously.
I suggest that you look in your router's pages and see what it shows for a WAN address and gateway. Make sure they are not 192.168.*.* addresses... I doubt it, but check.
Back on your original configuration. You had set the router up with the QOS:

Some say the original QOS is not so goodhttp://www.dslreports.com/forum/r24506811-wndr3700-appreciation and look to DD-WRT or other firmware. https://www.google.com/#psj=1&q=WNDR3700+qos+voip+dd-wrt+OR+tomato
Another configuration to try with the OBI in the middle is to put the OBi back into router mode, and to turn off the DHCP in your Netgear router. That might be called access point mode. See if test speeds are OK... then set up QOS in the OBi.
It may be that the OBi just cannot keep up with a fast connection as well as your router.

I wouldn't be at all surprised if putting traffic through the OBi as a router is significantly slower than putting it through a modern router. That is just based on my professional knowledge and experience of the innards of networking kit. I only have an OBi110 which has no router functionality so don't have any measurements to confirm my expectation.
What I don't understand is (in the original problem that started this thread) how the OBi and/or Netgear "can tell the difference" between calls going to landline phones and calls go to cellphones! Or have I misunderstood and the reference to cellphones means calls going out from the OBi via OBiBT and a cellular carrier (rather than going over the internet)?

The issue is that I cannot have a satisfactory call with someone on a cell phone from my voip phone. Calls to other phones are OK. The only reason I can think of is that perhaps cell phones introduce latency greater than a normal internet connection and the combined latency causes packets to drop ==> call breakup.
PS: My internet connection is still terrible: 5.67Mbps on a 28Mbps service. Usually I am in the 30+ range. I suspect the OBi is unable to keep up. When I get some time I will try and test the following:
PC ==> cable modem
PC ==> OBi ==> cable modem
PC ==> Netgear (30Mbps)
PC ==> Netgear ==> OBi ==> cable modem (5 -15Mbps)
When connecting the OBi in the traditional way (to a port on the router) I have dropped packets, so I guess that makes it an issue for Netgear support. I think that is my next option. If Netgear doesn't have a solution, then I could try dd-wrt as Shale suggests. My research on the dd-wrt firmware was that it wasn't as fast as the factory firmware, but if it solves the problem it may be the better choice. The only other thing I haven't changed is the voip service (voip.ms),so I suppose I could try a Google talk session.
This is a lot of work to install voip (sigh).
Shale:
Good ideas.
Also remember the **9222222222 echo test number.

@ajaxmike
1. You haven't said explicitly what the problem is with calls to cellphones. When you make a call to a cellphone do you have bad quality only from you, only to you or in both directions? And if you have an incoming call from a cellphone how is the quality in each direction?
2. I don't really buy your 'theory' of extra latency causing dropped packets.
3. If you look at the Call Status page on the OBi's web server during a call there is quite a lot of technical info. Can you spot significant differences between calls to landlines and calls to cellular phones?
4. That you had the same problem with the Linksys ATA and that the OBi directly connected to your modem is fine both point a finger of suspicion at the Netgear. I sometimes see posts saying to try disabling the ALG in the router if enabled and vice versa though I've never used a router which made that toggle available to the end-user. It does seem to be available on yours. http://support.vocalocity.com/kb/netgear-wndr3700/.
