You apparently have one of the bad Grandstream ATAs (so, it happens), and you refuse to trade it for a PAP2T since you don' t have/want a router. Why are you not telling VOIPo to send you another (working) Grandstream?

Sorry, but what am I missing something here? I don't think the ATA you have now is going to get any better.

Tim, are you shipping out any replacement Grandstreams, for those that need them?
