SIP is an application control signaling protocol proposed by IETF. As the name implies, it is used to initiate a session. It can be used to create, modify, and end multimedia session processes attended by multiple participants. Participants can
I recently found out doing a sip capture on a FreeBSD system is a little different than centos or other Linux distributions. here is a easy to use command that will grab the SIP packets from TCP dump. this will give you an easy to read text file for

How does WebService real-time interface implement?
The current project needs to implement such a function, WebService real-time playback interface.
At first, I didn't understand what this function was. In general, I used a browser to view the video captured by a remote camera and play the Mic to collect the audio;
I learned the following solutions: 1. ActiveX; 2. WebRTC; 3. Flash + Red5;
Based on our current VoIP server, we use the open-source
IPPBX or an operating system. Many voip virtual operators use this as their own operating systems. Provides a bsstructure management interface.
3. YATE: Open-Source SIP server for cross-platform Linux and Windows. It is very easy to install in windows. Other aspects have not been tested.
4. SER: The heavyweight SIP server in Linux is disconnected. It has rich functions and is also the system choice of many
With the popularization of VoIP technology, the security of VoIP voice communication has aroused more and more widespread concern in the industry. But where the security threats of VoIP originate, this should be the first step in the industry to systematically address VoIP security issues.
In October of this year, VOI
Many enterprise users usually deploy VOIP network phones as one of the most important considerations when deploying network applications. In terms of enterprise-level mature network application models, the trend of such VOIP phones becoming the mainstream communication applications of enterprises is becoming more and more obvious.
In fact, according to a recent survey by Telappliant, 100 of the 41% companie

IOS background running
WenyiI learned from the apple documentation that a general application can get a certain amount of time to run related tasks when entering the background, that is, it can run a short period of time in the background.
Three other types can be run after,
1. Music
2. location
3. voip

principle.
Actually, you can modify the call to display this stuff. Any engineer or technician in a phone, communication, network call (VoIP), or mobile phone manufacturing company knows it, just like hackers must know what an IP address is, and they can do it easily without any difficulty ......
First, learn a little about data transmission over the telephone network. The materials are as follows:
The following data is taken from: the principle of
SummaryThis article introduces the principle and basic implementation process of VoIP, and analyzes the composition of audio latency in the Ethernet environment. The experimental results show that the audio latency in the Ethernet environment is mainly composed of the buffer latency and API call latency, and the most important part is the API call latency. This paper proposes a method to reduce API call latency using directsound interface functions, a
Execution in the IOS background is the content described in this article. Most applications will be paused shortly after they enter the background status. In this state, the application does not execute any code and may delete it from the memory at any time. Applications provide specific services. Users can request the backend execution time to provide these services.
