IOT command (based on sip) client API design for java, iotsipThe Iot Device Control we implement is implemented by extending the sip protocol. Because pjsip is implemented based on pjsip, while pjsip uses C Programming, how to make the business layer (android end, java) easier to use the provided command API is the focus, the original method is to encapsulate (C ---> jni ---> java) from the underlying c, wh

Strict routing and loose Routing 1. The address list of a loose route does not list a complete and strict path, but only provides some key points in the path..You can use the automatic route selection function of the vro to route data between key points. data packets must also be copied during data packet sharding. In a SIP message, if the parameter in the first Route Header field contains the LR parameter, It is a loose route. 2. Strict routing re

It can be used to create, modify, and end multimedia session processes attended by multiple participants. Participants can communicate with each other through multicast, unicast, or network connection. There are clients and servers in the SIP. A client is an application that establishes

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.

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. Therefor
