I have used GV successfully for several months. In last 2 weeks callers complained my voice was garbled. Sometimes I answer the call and the caller can't hear me at all. I have tried prioritizing the Obi using the Qos settings in my router with no improvement. I replaced all cables to the Obi with no improvement. Power cycled the Obi with no improvement. I tried logging in to my Obi using the IP address and my browser says "ERR_Connection_Reset". Ii tried lowering the Tx and Rx gain settings with no improvement. I can login to my Obitalk account and all looks normal.
What do I need to do to get this fixed? Has my Obi110 gone bad?
This is likely a problem with your home network or your ISP connection. If you can't log into the OBi via its IP address, then something's wrong with your home/office network configuration.
This has nothing to do with SIP ALG, since GV uses XMPP, not SIP.
It also has nothing to do with a "CODEC mismatch", since Google Chat/XMPP only uses G.711 from the OBi to the GV infrastructure, and it's always negotiated automatically, regardless of what other CODECs you may have enabled. If you didn't have G.711 enabled, it wouldn't work at all, and any other enabled CODECs are ignored.
You'll have to sort out your local network issue. You can also perform a definitive test of your ISP's ability to reliably support VoIP, by performing the G.711 VoIP test on this website:
http://myspeed.visualware.com/index.phpThis test will eliminate your OBi and GV from the loop, as it simulates a true VoIP "conversation" between a Java applet on your computer, and an endpoint you select, and it reports the results as a MOS, or Mean Opinion Score. MOS is based on a calculation that takes into account not just peak data speed, but also jitter and dropouts. A MOS of less than 4.0 is unacceptable for VoIP, and indicates an ISP or local network problem. Run the test immediately after a failed GV call, and run it several times to different endpoints to get an average score. The regular speed test websites are worthless for determining whether or not your network connection can reliably support VoIP.
