The Disadvantages Of Using Voip
This is the reason why you 1 way traffic in some scenarios. If both NAT devices are non symmetric NATs they'll get appropriate information through STUN and voice flows both ways ok. If device is symmetric and also the other is non symmetric only one among them can get the correct info through STUN and data can pass one producing make certain way speaker. If both are symmetric consumption hear almost everything because traffic can't complete either NAT device.

TCP mandates that one end point must first build a connection for data always be sent returning. As we know you have inbound and outbound robber. If I am making an outbound connection then it is an inbound connection at another end. And inbound connection requires port forwarding which we are lacking set up in this. Also for data become sent back the socket MUST BE ESTABLISHED. Essential important as it would be not essential of UDP. UDP is connection-less remember (see The differences Between TCP and UDP for more info). It may well send data without ever being associated with the remote location. This is the key difference between TCP and UDP that permits you to traverse a NAT using UDP without port forwarding. The technique is called UDP hole kickboxing.
VoIP is actually useful because it allows one to call near enough everyone from wires of the internet. Is actually why because the quantity you are calling really has also to have similar VoIP features or functions. Plus, the price availing VoIP is rather a lot less inexpensive than particular phone line features.
The problem here proven fact that SIP doesn't know in order to behind a NAT. Let's say your local switch IP is 192.168.1.1 and the remote IP is 192.168.2.1. Although NAT modifies the SIP packets to everyone IPs when traversing the web it does not change the actual data ultimately SIP packets themselves (the payload). It's the payload is made up of the information about what ports and IP addresses to use for the actual phone telephone call. The local VoIP tells the remote VoIP (via SIP) to send voice data to its local IP of 192.168.1.1 and vice versa. As we all know this in no way going perform as internet routers drop packets from and to private IP addresses. The actual call is defined and the UDP voice data actually starts transmitting it always be sent to private IP's and therefore dropped. How exactly do we fix this in turn?
