so i have the obihai 110 and im using GV. when i call people, i often cannot hear them after 1 minute, sometimes when people call me, the call doesnt go through... sometimes when i try to use the phone, it says i have no service. i followed the instructions on the obihai website perfectly... im not sure what's wrong. i have a yahoo email, does that matter? i was skimming some posts and it seems that might cause problems... its like my service is on and off...
