The problem here normally SIP doesn't know is actually very behind a NAT. Let's pretend 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 individuals IPs when traversing the online market place it doesn't change the particular data each morning SIP packets themselves (the payload). Is usually the payload that has got the information regarding what ports and IP addresses to use for a lot more phone call. voip call service tells the remote VoIP (via SIP) to send voice data to its local IP of 192.168.1.1 and the other way round. As we all know this is never in order to be work as internet routers drop packets from likewise private IP addresses. Once the call is defined up and also the UDP voice data actually starts transmitting it tend to be sent to personal IP's and thus dropped. How exactly do we fix all of this?
The problem arises because VoIP uses dynamic UDP ports for everybody call. This causes problems when traversing a NAT device for two reasons; the NAT device changes supply port of outbound packets as a part of the NAT process. Subsequent is self confidence is because UDP because of its demands is designed for one way traffic (broadcasts, video stream etc). Where TCP users are bi-directional across the one connection UDP get a 1 connection for inbound and another for outbound meaning they can use different ports. Generally if the inbound connection uses different ports whilst the outbound connection the inbound traffic is dropped mainly because the NAT device does never a mapping for it in its NAT workplace. If you are confused sustain I suggest you educate yourself on NAT first.
