How do you know, conclusively, if it's dead or not? Have you tried another (different, known-to-work) telephone and cord?
--I plugged a wired telephone into port #1 and got nothing. No dial tone.
--I dialed the phone number for the phone plugged into port #1 and got "we're sorry but you've reached a number that has been disconnected........"
--I plugged the same wired telephone into port #2 and got a dial tone and able to dial out.
-- I dialed the phone number for the phone plugged into port #1 and the phone rang as expected
Have you looked at the device status in "expert configuration" mode? If not, do so. The voltages should be similar (within a couple of volts) to my screenshot attached below.
--I searched everywhere after logging into
obitalk.com and could not find where the "expert configuration" mode is??
Unplug BOTH phone cords from the device. Power it off and on again. Plug in a one-line telephone into the PHONE 1 jack. Pick up the phone. The LED on the OBi for that line should start blinking in a regular on/off cadence, and you should hear a dial tone. If you don't, it's fried. There are no user serviceable parts inside.
--I'll try this when I get to the office in the morning. The unit is only 6 weeks old.... Do you know if there is a warranty?
