example, sip and h323 protocols belong to this type. Sip/h323 obtains its data channel through the signaling interaction process and negotiation, which is generally Audio streams encapsulated in RTP format. That is to say, purely detecting the RTP Stream does not mean that this RTP stream is created through that protocol. . The complete analysis can be obtained only by detecting the Protocol interaction of

, but the traditional telecom market was not greatly affected. It seems that their business is not in conflict. Until the emergence of VoIP. In fact, the VoIP technology began to appear in 1990s. However, due to bandwidth restrictions and immature technology, the quality of calls cannot be guaranteed, therefore, it is not favored by consumers like Im. However, bandwidth is no longer a problem today. The technology of VoIP is constantly growing and gradually maturing. Both signaling connection

of VOIP in enterprise networks. For example, if a VOIP Terminal in an Enterprise Network wants to be accessed by the outside world, it is difficult to maintain the network by ing all the VOIP terminals to the outside world on the NAT gateway. At the same time, this ing has poor scalability. In NAT gateway, H323 and SIP application-level gateways must be implemented. Currently, most devices do not support this function, this means that enterprises are

@internat.ion.al // 0Match All characters starting with 00. If we call: 0099123456, the module returns: IAX/99123456@internat.ion.al/0099123456. The/0 and/1 parameters in the following target are parameters, and the preceding characters are/0. In this example, 0099123456 AND/1 are parameters between the first/(/) in the match, /2 is the second/(/) parameter in the match. /1 is 99123456 In the example. Route 112 and 911 to pots (common telephone service), that is, any channel of E1, and force the

, ensuring the security of this protocol is a very important part of the VoIP Security System. In practice, the protocol uses Abstract Syntax symbols to encode the group. Therefore, it is difficult to take some security measures. In other words, there are few security solutions for this abstract syntax symbol. This is mainly because it is much easier to understand the content of the H.323 stream than to understand the stream of other existing protocols. Because of this, many attackers prefer thi

The PIX two ports are actually used. The ultimate goal is not to use NAT to let the internal network address directly out, both inside and outside the PIX are cernet addresses. No NAT is used in configuration 1, internal nodes cannot go through PIX With NAT in configuration 2, internal nodes can go out via pix The two configurations are the same except for Nat. Please help check to see how to do it without NAT. Thank you! Configuration 1: No NAT is used, internal nodes cannot go through PIX : Sa
