Help: no sound on Obi202 with GV
jpotkay:
Hi all,
I purchased an Obi202 some time ago, stopped using it when they dropped GV support, and just tried to get it up an running again. After updating the firmware in my Obi202 and in my router (TP-Link Archer C9 v1), I can make and receive calls, but I don't hear anything through my phone's speaker (Vtech cordless phone). The phone that I call can here what I'm saying, but I can't hear them. I also don't hear the phone ringing when I place a call. Finally, I can't hear any audio when I try to do an echo test. (**9 222 222 222). Any help you can provide would be appreciated.
Steps I've taken so far:
1. Did a factory reset of my Obi202. Installed the newest firmware. HardwareVersion: 1.4, SoftwareVersion: 3.2.2 (Build: 5921EX)
2. Installed new firmware on my router (TP-Link Archer C9 v1.0, Firmware Version: 3.17.1 Build 20180125 Rel.56387n)
3. Re-setup Google Voice through my Obitalk Dashboard.
4. In Google Voice, made sure that my calls were forwarded to my Obi device, not Talk/Chat or another phone.
5. Made sure the correct ports were open on my router as specified here, and set a fixed IP address for my Obi device:

6. Checked for a SIP ALG setting for my router, but it does not appear to have one.
Here is the Call Status when I make a call with my Obi202:

Hi Joe:
Your call status data looks fine. It looks like a normal call to me. You didn't mention the glaringly obvious test: try a different telephone (not the Vtech) plugged into the OBi.
Also, use a PC connected to the same LAN. Sign into the correct Google account that has your Google Voice number. Go here: https://hangouts.google.com/ and call somebody. Does 2-way audio work?
SteveInWA:
I assume somebody with a TP-LINK router will chime in here, but a quick Google search on "TP-Link Archer SIP" has a lot of hits. The articles seem to agree that SIP ALG is enabled by default, which is no good, but turning it off only works until the next router re-boot. That could easily cause one-way audio.

Steve-
Many thanks for the replies and help. I sincerely appreciate it.
1. I just tried making a call from Hangouts on a computer on the same LAN and it worked just fine with audio in both directions. I also had another cordless phone that I just hooked up to the Obi and it also had the same no audio issue.
2. Yes, I can not find a SIP ALG setting in the router configuration settings. Copied below are the most related settings, which are all enabled by default. I tried disabling the ALG settings with no luck. I'm beginning to think I need I new router. I'm going to try contacting TP-Link to see if they have any suggestions. Please let me know if you have any other ideas.
Thank you again.
Best,
Joe

So, that at least confirms that your Google Voice number is working properly, although different ports are involved with Hangouts vs. GV/OBi.
Did you try using a different telephone? It would be rather embarrassing if that was the problem.
I would at least go into the router's settings and DISable every one of those ALG settings. None of them are necessary.
If all of that fails to solve the problem, you could take your OBi over to a friend or relative's place, and try it on their network, for comparison.
