Phone jack not working
yaworski:
I've had a single line Obi200 since December. It was working fine until the other day. No dial tone on either of the two phones in my house.
Odd, the green light for the phone was lit. I got a phone and a new cable and plugged it into the box. No dial tone. Tried another phone and another cable and the same thing.
I tried calling and the green light flashed to indicate an incoming call but nothing happened with the phone.
Who do I call about a problem like this?

How were the two phones connected to the single jack of the OBi200?
yaworski:
A home phone network is a bus. If you connect your ObiTalk box to a wall jack, every pihone on the net is connected to the Obitalk.
So my Obitalk box is plugge into a wall jack near my router. I then have a phone in the kitchen and another in the living room.

All that is fine until an unwanted voltage is introduced to that "bus" and fries the SLIC chip in the OBi. The SLIC chip is the interface between the analogue PHONE jack(s) on the OBi and the digital processing. Fried SLIC means no dial tone etc.
So where can an unwanted voltage come from? In most cases from an external telco line that has not been (properly) disconnected from the internal house phone wiring. Sooner or later something can happen such as:
1. A thunderstorm with a lightning strike causes a voltage spike to appear on the cable, even at some distance from you, and it travels along the external cable into your OBi. Zap!
2. The telco, who owns that cable (you do not) tests the cable. One of the tests puts a voltage between the two wires. Your OBi's PHONE port is subjected to that voltage. Zap!
The acid test is to log into your dashboard at obitalk.com and enter Expert Mode. Unplug the phone from the OBi. Then click on Status and then on Phone Port Status. Look at the VBat and TipRingVoltage numbers. If they are zero or blank then your SLIC chip is dead. No repair. New OBi time. And if you don't know what "properly disconnected" above means get someone who does. Else you will sooner or later have another zapped OBi.

I thought of that when Verizon discontinued copper lines in my area. Disconnected the phone line where it came into the house. That's not the issue.
The issue was getting ahold of someone from technical support.
