Google Voice One Way Audio
Steve56:
Been using the Simonics gateway with multiple separate Obi units happily for several months now. Recently, within the past two weeks, I've been noticing issues with one way audio. It started with my wife calling my cell phone from the house. She could apparently hear me but I couldn't hear her. Now it's changed to where I can hear her fine but she hears nothing but silence on the other end of the line. Calling back works just fine and we can hear each without issue. This issue has been replicated calling numerous other phone numbers as well and only started about two weeks ago. At first thought it was my cellphone at fault, but I suspect it has something to do with the Obi, Google Voice, or the Simonics Gateway. Any suggestions or advice to fix this issue?

When you are on an active call, check the call status. Enter OBi Expert, click on Status then click Call Status. The Audio Codec should be G711U for tx and rx. You should also have RTP Packet Counts for rx and tx.
You could try turning off SIP ALG in your router. Some routers don't have this option. You could also port forward the RTP ports. The port number range is found here in you OBi.
Service Providers -> ITSP Profile X RTP -> LocalPortMin/Max
FYI my OBi110 GV stopped working, but starting working again on December 18th and is still working. There is also 3rd party firmware with new certificates that fixes the OBi1xx GV problem.

Thanks for the help. Here's a screenshot from my most recent test call with the aforementioned one way audio issue.
Everything seems to check out so I haven't a clue what's causing the issues.
Running DD-WRT on the router in question and based upon my cursory sleuthing, there doesn't appear to be any such option to disable.
I'll try the port-forwarding and see if that fixes things.

Any change with the obi (model #?) hooked up directly to the modem?
Steve56:
I haven't tried connecting it directly to the modem but I did go through with updating the firmware to that which was mentioned by azrobert. Even went so far as to remove the Simonics gateway sign in info and instead connect directly to Google Voice as I once was able to. Outgoing calls still had the exact same issue. Sometimes the call would work fine and others there would only be audio on one end of the conversation. I'm totally lost at this point and don't know what to do. I contacted Bill Simon and he reported that isn't anything wrong on his end.
The last straw is to replace my router with one that's brand new.
