How Voip Services Work
The problem here may be the fact SIP doesn't know it can be behind a NAT. Suppose 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 the people IPs when traversing the world wide web it does not change the particular data each morning SIP packets themselves (the payload). It's the payload consists of the information regarding what ports and IP addresses for the actual phone contact us by calling. The local VoIP tells the remote VoIP (via SIP) to mail voice data to its local IP of 192.168.1.1 and the other way round. As we all know never for you to work as internet routers drop packets from comes with private IP addresses. Once the call is to and the UDP voice data actually starts transmitting it is sent to personal IP's and thus dropped. Exactly how do we fix this important?
