latency/lag using Google Voice & Obihai OBI100

[GunsMadeAmericaFree]

According to half a dozen speedtest results I've written down over the past month, we have pretty consistent results from Time Warner Internet:
ping 13ms download 2.3 megabits upload 1.2 megabits

Despite the fact that this seems fine for Netflix videos over our Roku, results with the Obi100 and Google Voice don't work that well. I thought that if anything, I'd be experiencing problems with Netflix way before I had issues with VOIP.

I set this up to be our primary landline phone, and there just seems to be too much lag. What I mean by this is that I and another party will end up talking over each other, and it makes conversations difficult. I have had several folks say that it seems like I am not hearing them until a couple of seconds after they say something. It causes a disjointed phone conversation. It has pretty much been like this from the beginning - some days are a bit worse than others.

Unlike the Roku, which is hooked up using wireless N, the Obihai is hooked up with an ethernet cable to our WNDR3400 simultaneous dual band wireless N router. According to the report I got from the phone hooked up to it, it is set up to communicate with the router in full duplex mode. I thought it would work pretty well, since there is no possibility of any wireless interference.

Can anyone suggest a setting or two that I might want to tinker with on the OBI100, in Google Voice, or perhaps the router, which might be able to get rid of this latency lag? Or, maybe an experiment or two that I could conduct which might help get to the root of the problem?

Thanks very much!

Remove everything that is taking bandwidth from your network (Netflix, downloads, several wifi connections) and place a call. If the call is better, then you most likely just need a faster connection.

I did not notice any call improvement after shutting off the computer and Roku, which are the only two things we have that ever connect to the WIFI.

I ended up trying three things:

1) I set my Obihai to use full duplex, & use Gigabit speeds for Ethernet
Dial *** 0
Enter option 27 and press #
Press 1 to set a new value
Enter a value of 1
Press 1 to confirm/save
Hang up

2) enabled QOS on our router

3) in the QOS settings, I set ethernet 1 to High Priority
(ethernet #1 is the one the Obihai is plugged into)

I've done a few calls this morning, and there is a MARKED improvement to the call quality. Latency seems to essentially be gone, and now we can both talk at the same time without it seeming to cancel the other person out.

I guess the answer is that this internet speed is fine for VOIP, but both the Obihai and the router needed to be optimized for the VOIP a little bit.

Have you tried a different SIP provider? I always had a delay with GV. None whatsoever with Axvoice on my OBI110. Most SIP providers have a 30 day trial
