Hi all, i have been using a Linksys PAP2 ATA for a long time with the business VoIP provider Switch2Voip , it's an excellent device, today i changed my internet  router and now i can't hear no sound, i hear the dial tone but when i  dial there is no sound, the phone doesn't ring.

My device  is registered with the sip account, again i would like to emphasize that  it was working before i changed my modem. Anyone with the same problem?
