I have a OBI202 set up with GVoice on SP1 and Phonepower on SP2.
Recently GV went away. Just would not hook up. Apparently I finally was caught out by the changes at Google Voice. So I took a deep breath and followed SteveinWa reset and reup directions to get it working again. Excellent directions and Google Voice successfully on Ph1. Success!
However, I could not get my PhonePower account to hook up from the OBItalk interface. So I called PhonePower and was told that they no longer support OBItalk. They sent me instructions to set it up manually, by accessing the OBI202 directly to input the settings. Have tried 5 times - no luck. I do have my correct SIP password from the PhonePower website. I recontacted them and they said an expert would call me - that was 3 days ago. Not good.
Anyone else had this experience and can offer help? Making firmware changes to the OBI which negatively affects other VOIP providers than Google seems a mistake.
