Emergency need for Obi200 SLIC bypass
n4mwd:
Normally yes, but in this case, I noticed that the board has parts on both sides. This usually means that there are two types of solder used that have different melting points. This makes trying to desolder the chip a bit like playing russian roulette. Still possible though, just harder. Probably would cost more than the $50 to buy a new one.
Anyhow, I'm wondering if this is a common failure of the obi200?
SteveInWA:
SMH.
I never understand people who think it is worth their time to sink hours and hours of research and fiddling time on repairing low-cost, disposable consumer electronics, vs. buying a new one. Nor do I understand someone who would waste so much time fiddling around with this, vs. dealing with a hurricane or otherwise making better use of their lives. Just because it is theoretically possible to do something, doesn't make it worthwhile.
Nor do I understand how anyone could jeopardize the health and safety of elderly people with a home-cobbled kludge solution.
I call BS on the "can't use a cell phone". If someone can push keys on a standard PSTN telephone, then they can push keys on a senior-friendly, big-button cell phone. Consumer Cellular, for example, sells zillions of these phones to seniors.
If vision or dexterity problems are a barrier, then a smart speaker like an Amazon Echo Dot or Google Home Mini that can make calls via voice commands ("Call Bill") is a cheap and effective solution.
As Geoff pointed out, and as I have said twice already, you cannot fix this yourself. You'd need a commercial-class SMD de-soldering and soldering system, and the packaging for this chip is very sensitive to excessive heat during soldering. It is not a DIY repair, to say the least. And NO, there are no components external to this module that would cause the failure. This is not a military-grade product, and yes, the SLIC is the front-line to the external world of power surges, lightening strikes and other failures that will fry the device. If you want to avoid this, install surge protectors on ALL the things attached to the AC and telephone wiring, including a device like a APC PTEL2 to protect the analog phone line.

No offense, but you greatly over estimate the intellectual abilities of an elderly person with dementia.
You win. I promise not to try to fix this one.
The kludge was to make it work with Bluetooth since the only working ATA that I have available is a grandstream which doesn't support BT. Echo and that stuff requires an internet connection, but if thats still working, I wouldn't need BT to bypass the VOIP provider.
I ordered a new obi302 on amazon almost a week ago and it still hasn't even shipped.
The hurricane is coming back this way, but still turning north. Wind gusts up to 220 mph. Its the biggest one I have ever heard of. If it turns north like they say, then we'll only see cat 1 force winds which is nice picnic weather for old time Floridians like myself.
