I am having difficulty with my device with callcentric,
sip.iptel.org and google voice. All 4 SIP are showing "service not configured". I installed express talk softphone and use the setting for callcentric and
sip.iptel.org, and after I dialed the numbers express talk will ring. So I know it is not the problem with the setting. I don't know if it is the device itself with problem as I have already pass the 30 day return at amazon.
Does anyone else have idea what might be wrong? Google voice worked at one point and then stop working. I deleted and reinstalled but nothing worked. The only thing I can think of is I used obivoice, now verstalink and it did the automatic thing to register my obihai. Now that I don't use obivoice after the free trial and I reset the device, it might have been around that time I can't get another other setting working.
