Other person can't hear me.
MYOBi:
If this helps anyone:
I have Netgear WNDR3700 router. I have been using OBi for about a year, I never had this stuttering problem. Last week, I purchased a backup router that was on sale "Belkin F7D7301 Share Max N300 Wireless N+ Router", and loaded Tomato firmware on it (tomato-K26USB-1.28.7497.1MIPSR2-Toastman-RT-Ext.trx). I started to observe this stuttering problem, immediately only on Google Voice on SP1. When I call my Obi from work or cell phone, there is terrible stuttering, it is impossible to understand the AA prompts. I enabled QoS, did not help. I also have SP2 service from CallCentric, it worked OK but with some degradation in quality.
I immediately removed the Belkin and started using Netgear, then, problem disappeared.
When I have more time, I will try Belkin again, maybe with different firmware.
Edit on 5/21/2012: Enabling Qos with Default settings in Toastman's Firmware caused this problem. I also switched to another version of Toastman 7498.1 release. I do not see this problem any more, QoS disabled.
RonR:
FWIW, I've never tried any of the Toastman releases, but I have been using tomato-K26USB-1.28.9054MIPSR2-beta-Ext.trx for the past year with OBi's and haven't experienced any problems.

Having the same problem.. but when i call from my computer on GV its the same problem.. so im hoping its GV and not my obi

I have the same problem reported in this thread. Here is my email trail with Obihai Support Team. I am sorry that in the end I still do not have a resolution.

We have the following two problems
a) Many times we can hear the other party but they cannot hear us. I have tried to restart the Obi100 by pulling the power and putting it back it in.I have tried to restart with ***9 and then 1 to reboot. But the issue still exists
b) Many times there is lot of crackling in the sound we hear.
I have set up Google Voice on SP1 and Voip.ms on SP2.
Thanks in advance but let me know whether you need any other information
Obihai Support Team
===============
Do the remote end not hearing you at all or do they hear you choppy ?
What is your internet link ? DSL / Cable / Satellite ?
What is your upload/download bandwidth ?
Try to set/configure QoS on your router.
Set it to give highest priority for OBi, and give "upload badwidth" to 100Kbps.
Google Voice requires usage of 100Kbps bandwidth, so this amount needs to be "reserved" for OBi.
Typically the QoS setting is for what ip address of the device.
Reboot your router after you change this setting, to make sure that it is remembered.
For QoS configuration, please look at your router's manual. Here is an example for Linksys router model:

Thank you very much for your prompt answer.
I have a DSL connection with 6MBPS download and 500kbps upload. It has been working ok till around last month. We have started having this problem recently. When I searched on internet, I saw the following thread and seems lot of people have reported the same issue

===================
Configure your router to allow outgoing packets on UDP port 19305.
You can also try to put OBi’s IP address in your router’s DMZ.

I have added UDP port 19305 to the list of ports to be forwarded to the Obi100. I had already added 5060, 5061 and 16000 - 16991. I will see how it goes.
Thank you very much for the answer.

I added the ports, as shown in the picture below. (192.168.1.2 is the Obi100 device). Still no luck. It is always the other party that is not able to hear us. This is only on some calls, There are calls where both parties can hear well.
<picture> DD-WRT --> NAT/QOS --> Port Range Forwarding page </picture>
Next I am going to add the Obi100 to the DMZ and see whether that works. Thanks for your answer.
I want to bother you with another issue I have. The line is choppy sometimes. I am guessing that this happens if the internet bandwidth is in use by other applications like NetFlix. I wanted to confirm that this can be resolved either by increasing the bandwidth - a higher MBPS or QOS. My current bandwidth is 6 MBPS down and 500 KBPS up DSL conection.
Obihai Support Team
===================
Our instruction in
http://www.obihai.com/FAQ.html#ports-to-keep-open-on-my-router
is to allow outgoing packets on these ports.
Not port forwarding them to OBi (incoming)
For choppy audio, set QoS for your router.
Give OBi highest priority and bandwidth amount of 100Kbos

Well opening the ports and port forwarding aren't they the same? When a request comes from internet to Obi100 on port 19305, the port forwarding allows access to that port on Obi100, which in other words means that that port is open.
I am trying to place the Obi100 on DMZ for few days. I will know whether that works
Thanks for your answer.

I have put the Obi100 in DMZ. So no port is blocked. I am still having the problem of other person not able to hear from my phone. I reset the Obi100 to factory defaults and just set up Google Voice. I still have the problem.
I have been using Obi100 since early last year from the time Obi100 came out and I have been using the same router since then. I have not had this problem till sometime last month. And when I visited Obihai facebook page, I find that an update was pushed out. Is it possible for me to roll back to the firmware prior to that? I never had this issue at that time.
Thanks
Obihai Support Team
====================
You need to allow outgoing packets on udp port 19305.
When you do “Port Forwarding”, that is incoming packets.
You can leave OBi in the DMZ.
The current firmware that you have, 2711, is good. There is no reason to downgrade.

Thanks for your mail. I have done the things you suggested. I am still having the same problem of other party not able to hear anything at all. Is there anything else that I can try? I am afraid right now I have hit a wall and it seems like I have try some other product. It has been working well till last month. Thanks for your time.
QBZappy:
sramaswamy,
You didn't mention, however I assume you are having problems with both the GV & voipms. Just a few things to see if there is anything unusual:
1) While in an active call look at the call status and note the codec being used and the other info. Test using both SPs.
2) As a last resort set up the OBi at a friends house and see if it can be reproduced there. (This is a pain, I know)
3) If you could get your hands on another brand of ATA you could compare and conclude if it is a router or ATA related problem.
Disconnect the OBi and check the following (OBi not involved in anything):
4) Does making a call using a soft phone client work properly when connected directly to voipms?
5) Does calling the GV number using a cell phone, making the call directly to the computer work properly?
Good luck.
