I have a 622 and the Vonage. The Caller ID works fine, but it doesn't seem to be able to dial out successfully, and I was wondering if there were any other prefixes besides *99. When I had DTV I used #034 to slow the modem and it worked. I already have Vonage at the highest setting, so *99 really doesn't help. The 625 that is closer to the router dials out fine, I just don't want any unexpected fees to pop up. And the box is trying to dial out about 12 times a day, can get annoying when you are on the phone.
Thanks for any help.
