Thanks. I'm not sure what the **5 method is; I googled around and couldn't find the procedure. I don't think it matters, though. I did the reset, and it appears as you said, but after 10 minutes, the power LED just slowly blinks and I still don't have dial tone. Bummer... I think I only had this thing for about 2 years.
1. Power LED flashing green? Check that you have the WAN or internet socket on the 202 connected to your router. Using the LAN socket instead will not work.
2. Irrespective of the above, a powered up OBi should always give dial tone. Either the phone, the cord or the OBi is faulty.
3. The **5 procedure is how you register a device to the Obitalk portal so that it appears on the Dashboard. Instructions are in the Quick Start Guide supplied with every OBi or downloadable from obihai.com. However until you get dial tone on a phone you are stymied.
