If there is a cable Internet connection, your downline is 2 to 10 times faster than your upline. As a result, you may hear your partner clear as a bell along with may not hear you at several.

The problem arises because voip uses dynamic UDP ports per call. Stay together problems when traversing a NAT device for two reasons; the NAT device changes the source port of outbound packets as perhaps the NAT steps. The second is because UDP by its very nature is built for one way traffic (broadcasts, video stream etc). Where TCP users are bi-directional by means of one connection UDP get a 1 connection for inbound and another for outbound meaning these people could use different ports. If your inbound connection uses different ports when compared to the outbound connection the inbound traffic are dropped since NAT device does dont you have a mapping for it in its NAT bedside. If you are confused by now I suggest you read up on NAT first.
