I have paired two ObiBT with two obi202 whereas both devices are in two different countries. I see that both devices have pairing issue with any mobile of any brand, old mobile or new smart phones. Pairing isn't stable. Also ObiBT is good for one way calling, calls on paired mobile phone will not go to voip network (obi202 won't pick the call and transfer it to voip).
Is there any mobile that works flawlessly with ObiBT? Some brands do not pair at all like Nokia.. Other andriod phones sometimes do but again connectivity is lost after some time.
