Our small office uses VoIP lines and at some times our call quality is bad. We have been unsuccessful in correcting it; what else can be suggested?
If after trying the suggestions that have been made for checking your LAN network, bandwidth and connection reliability, enabling QoS on your router and you still experience break-up then you might consider a better more robust router that can handle SIP and QoS well. Two choices would be an Edgemarc or a router with DD-wrt or Tomato installed.
