Skype Could Be The Internet Cell
Business class VoIP works in quite similar way due to residential VoIP with one major difference. With business class VoIP a T1 is usually delivered to your office offering you with both VoIP voice lines and Internet service.

The problem here is often that SIP doesn't know can 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 the islands IPs when traversing the internet it does not change a lot more data in the SIP packets themselves (the payload). voip service telephone is the payload is made up of the the requirements for what ports and IP addresses to use for the actual phone call. The local voip tells the remote VoIP (via SIP) to send voice data to its local IP of 192.168.1.1 and or viceversa. As we all know this in no way going efficient as internet routers drop packets from and to private IP addresses. When the call would be to establish and the UDP voice data actually starts transmitting it will be sent to personal IP's and consequently dropped. So how do we fix that?
