Hi Oscar4572,Did you try entering your VBuzzer username in both the 'Phone Number' and 'Caller ID' boxes in the DTA-310 SIP Settings? I know it sounds wacky however I had the same problem that you're experiencing until I did just this.Cheers--www.netphonedirectory.comSpecializing in PC to Phone and PC to PC VoIP
