rport

3 Rport 3.1 solution description The obtained IP address is carried with the received parameter in the via header. In order to obtain port information, we also refer to this method, that is, to specify port information with the rport attribute in the via header. When Nat is used between the client and the server, the request may create (or refresh) a binding in Nat. In order for the client to receive the

(4) IPv4 to IPV6 protocol conversion, when at the edge of two heterogeneous networks (Ipv4/ipv6), Media Proxy can also provide these two kinds of IP protocol conversion. Media Proxy is an ideal device for deploying IPV4/IPV6 protocol conversions because of its special location. rport mechanism The IP address is obtained with the receive

Practice. It is not enough to know some knowledge. You need to practice it first. Now we have learned about the SIP protocol. Here we will share the practice process of a netizen's sip invite.

In the previous article, we analyzed the process of registering a message with a sip service. Next we will analyze the process of processing an invite request. From the handle_request_invite entry, the invite request processes the replace Request Header here. If it is replace, it is considered to be consulting. At this time, no new channel is created, but a channel is found (masqued ), in most cases, a new request is created based on invite. Therefore, we will start from here without considerin

). The first three types of external programs may share a nat ip: port pair.7. RTP ProblemsIn the message body of RTP, there is some information that UA needs to successfully communicate. The message body is called an SDP message.The problem is that the SIP terminal (UA) may not know anything about Nat. Therefore, IP addresses contained in SDP usually use internal IP addresses, that is, IP addresses known by the SIP terminal. In this way, when the communication peer wants to communicate with th
