Asterisk [1], asterisk
Asterisk [1] is an open-source Telephone Application Platform under the GPLv2 protocol. In short, Asterisk is a server application that can initiate a call, receive a call, and customize a call.

The Channel Driver Interface of asterisk
Due to the need of VoIP projects at work, I recently got in close contact with the asterisk engineering code. As for the great Position and Role of Asterisk in VoIP, I will not talk about it. Please refer to the previous article: astersik + radius simple strategy.

, asterisk records the source address and port of the packet (the Public IP address and port after the client-side Nat translation ), the voice stream of Asterisk will be sent to this address. The NAT gateway on the client side is automatically forwarded to the Intranet address of the corresponding asterisk.In this way, a SIP client (without ice) after Nat can already dial an

With the decrease in the cost of using VoIP, family and individual users are receiving more and more requests for using Vonage (or other similar products). As VoIP Communication continues to grow in the area of home calls, in addition, open source code projects are becoming more and more powerful. Based on this background and environment, Asterisk is a new product that can replace traditional PBX and is suitable for small and medium-sized companies.Th
