I am having the same issue as tsheehan7. where i was getting "To access your account, please enter your 4 digit PIN." message when using my cell. The only difference is that I have the obi100.
I did as you suggested,RonR, but now it always goes to my google voice mail when i call from my cell. like tsheehan7 says, it seems to work with every other phone, and I was able to do it prior to adding the obi100 in the mix. Any suggestions?
