Firmware 3.2.2 Build 5898) breaks PhonePower. Need to revert to 3.2.2 build 5757
rl4265:
How do I revert my Obi 202 to 3.2.2 build 5757. I'm out of warranty and am uncomfortable paying to fix a problem caused by Obihai's latest firmware update.
My Obi 202 and PhonePower have been rock solid for several years, but lately I have had issues:
I was on call using my home line, I got dumped and when I tried to reconnect, I got message that service provider rejected call, Code 403. I tried another number with the same result. Both numbers were Verizon numbers.
I reported this to PhonePower and they replied:
We have recently discovered that the most recent firmware upgrade by obihai
is the cause of the issues that you and other Obihai device users are currently experiencing.
Issues:
1) Constant loss of registrations (stacked registration agents showing on the account)
2) Calls dropping while in progress at random times.
3) Problems with ATT phones with built in answering machines.
The faulty version is 3.2.2 Build 5898EX You can Check your version by dialing * * * 01#
Until Obihai releases a fix to this version the only option is have Obihai Support assist with rolling
back the firmware to a previous version (3.2.2 build 5757) that does not have any known problems.

There wasn't a v.3.2.2 Build 5757EX. That build was v.3.2.1. The first v.3.2.2 I heard about was build 5859EX.
You can download the firmware here: http://fw.obihai.com/OBi202-3-2-1-5757EX.fw
If you're not sure how to load it, I recommend the Device Administration Guide, here:
https://www.obitalk.com/info/documents/admin_guide/OBiDeviceAdminGuide.pdf
I've read some things suggesting you may not be able to revert to that version, though. Something about a test in the newer firmware that prevents it. I'm not sure, though, so you should try it.
If that doesn't work, this is the last pre-Polycom version: http://fw.obihai.com/OBi202-3-2-2-5859EX-198839.fw which I believe you can "downgrade" to. it was pretty stable on my Obi200 running GV, voip.ms, and callcentric.
Best of luck. Let us know what happens.

Thanks so much. I downloaded the http://fw.obihai.com/OBi202-3-2-2-5859EX-198839.fw firmware as you suggested, but am concerned that I may break things. I decided to spend the $10 for Obihai tech support. The link didn't work well, but finally, I got an Amazon payments processing message, but no key etc.
I went through voicemail hell at Obi trying to unsuccessfully get to a live person, but was able to leave a message. Hopefully someone will phone me back. This is totally unlike the support I've gotten from Obi before and very disappointing. I hope that Obihai and Polycom can get it together. I've been a loyal customer since Obi 100 days and have recommended them to many others but if I can't get support, I have a real problem.
I'm going to leave things alone until I get guidance from Obi (or more direction from PhonePower) because I'd rather deal with random issues than change breaking everything.
I do have the device admin guide and will review it.

I have the same problem as the OP (except on a new OBI200), however I was able to downgrade to 3.2.2 5859 after figuring out how to prevent the auto update back to 5898. Unfortunately, that didn't solve the issue for me. I was able to get registration using the template that phonepower sent me, but eventually all 4 of the registration spots get filled up, and then gives me the 403 error.
I tried downgrading to 5757, but you get a checksum error
Kind of a bummer as my old OBI100 was working fine with phonepower until June, until GV failed, so I had to get the OBI200. Now the situation has flipped... no phonepower, but GV works.

I'm in the same boat. Obi needs to take a look at this.
