Basic setup, GV outbound voice quality choppy, inbound generally good
winger13:
My network comprises of a 50MBbps down, 5MBps up (although it can be as slow as 2.3Mbps up) connection via a Motorola Surfboard SB6120. That is connected to a D-Link DIR-655 and that is connected to the Obi110. I am using the latest Obi110 firmware (downloaded last night). I am using GoogleVoice on SP1 (setup as the "Primary Line") and a PTSN connection as well.
I have noticed outbound SP1 calls generally have been choppy tonight. Inbound seems good.
No computer on the network is on except this and it is NOT doing really much traffic.

1. Dial *** 0
2. Enter option 27 and press #
3. Press 1 to set a new value
4. Enter a value of 1 and press #
5. Press 1 to confirm/save
6. Hang up
7. Wait for the OBi to reboot
but I wanted to know what this does before I even try it.

Here is a test I just ran to see if this is a problem with Google Voice itself or it is an issue with the Obi110-initiated-call through the SP1 port (Google Voice).
I dialed **8 followed by my GV#
When GV picks up, I dial 2 to place a call to my test destination's phone no. (happens to be a voicemail system)
When the call is connected, the outbound audio this time is really good; no choppiness at all
This proves the outbound audio quality issue lies with the Obi110-initiated-call through the SP1 port.
Any advice how to proceed on clearing up the outbound audio quality?

It simply changes the OBi's Ethernet port from 10 mb/s half-duplex to 100 mb/s full-duplex. There's nothing risky about the change and it can be undone by repeating the steps but using a value of 0 in step 4 instead (or restoring factory defaults).
Even if it makes no improvement, it's probably a good change.

OK, so I have tested this almost every day for the past week+ since I got this unit.
Almost every weeknight around 5pm-6pm, for all calls to and from my OBI110 unit the outbound voice quality gets really choppy; however, during the day, voice seems crystal clear. I have not tested much on the weekend, but at least when I did after dinner, same result.
As it currently stands, the unit is not usable (I'd safely say) after 5PM every day.
Could I get some advice with this? Very light internet use in the house all day/night. My cable service is rated at 50Mbps/5Mbps. I have new'ish Motorola Surfboard 6120 modem, and a D-Link DIR-655 router.
As I mentioned above, SP1 is setup to Google Voice (as primary). When I Dial **8 + My GV # (forces calling GV via my connected PTSN/landline), then initiate a call using GV's option 2, the call quality is perfect.
This points to something with the internet and/or Google Chat (which my OBI connects to).
HELP!
RevKev:
I would try a trace or ping to the google server and check the latency during these bad periods. Although you have high upload speed (which drops to half at times), the latency of a shared cable line could still be a problem.

Good suggestion. Can someone point me out to the ip addy of the server which obi calls (gv) connect to
Also, what is a good latency value to stay under to ensure good quality?
