Emergency need for Obi200 SLIC bypass
n4mwd:
In my county, they only have one area code - 561. The original dial plan would route differently depending on the sequence of digits. If 1 is the first digit, then it expects 10 more digits and then automatically sends with the "S0" suffix. I think it was something like <1xxxxxxxxxxS0>. Local numbers were something like <[2-9]xxxxxxS0>. The OBI is configured for both Callcentric and my asterisk server. So something like <xxxx> is also there, but a # must be hit to send it to asterisk. The BT stuff is on top of all that.
The hurricane landfall dropped closer and is getting stronger. Wont get here until Tuesday morning though.
n4mwd:
I tried to get the configuration working properly, but I failed. I may play with it again later. Or, since the warranty is expired, try to crack it open and repair the hardware.
Fortunately, the hurricane is now headed off shore so the emergency is mostly abated. We might still get some tropical storm stuff or maybe some cat 1 hurricane winds, but nothing like the 190 mph gusts that we were looking at before.
Thanks again for your help.

Like I said: there are no user-serviceable parts inside. Period.

No, you cannot repair the 200. It's not a fuse issue. The SLIC is a self-contained, large-scale IC, which is not user replaceable.
The issue is that the line voltage is zero. I cracked it open. It uses a Silicon Labs SI32260-C-FM1 SLIC chip that costs about $6. I suspect that the chip is fine, but rather the DC-DC converters have bad caps and or diodes. Its probably doable, but like I said, I have more important things to do right now and I have a 302 on the way.

Why did you order a 302? I hope you realize that it a) can't support Google Voice, and b) unless you bought it from an authorized reseller as new, it might be locked to a previous service provider. This product is primarily intended to be sold by service providers, locked to their service, and not sold at retail.
I don't use GV so the 302 should work OK. I'm getting it from Amazon and there is no indication that its used or locked. I already have another one that's being used at my house. I remember that it required activation with ObiHau to get it to work right. The only issue I've had with it is that the ring current was not as advertised. I think it said Ren 5, but more like a REN 2.

It's not worth the time to dink around with your kludge solution. You have a f-ing hurricane coming. Use that time to get ready, and if it hits, just use your cell phone, you know, like a cell phone.
Sometimes, a technology "just because I can" solution isn't worth it.
The elderly people where this is at cannot use cell phones. Things would be a lot simpler if they would.
drgeoff:
The description of the SLIC in the summary data sheet includes
"A pair of built-in dc-dc converter controllers can be used to automatically generate the optimal battery voltage required for each line-state".
I fully expect the SLIC is not fine and would need to be replaced. True it is $6 but have you the means and expertise to remove that 60 pin device without causing damage to the circuit board?
