I have a US Robotics V.92 modem which I use to transmit info to my companies office in Tn. I used to have an analog line but have switched to VOIP. Now I can't transmit at all. It will dial out and connect but the it hangs and I get a communication error. Any ideas on how to get this to work again? I have Broadstripe VOIP and they use an InnoMedia MTA6328-R2e adapter. thanks, Jeff
