Requirements for VPN
Because the VPN is for the Enterprise User Service, relates to the enterprise normal operation, therefore the following from the user angle analysis to the VPN several requirements.
VPN availability: That is, the established network can meet the requirements of the user's business. After the enterprise user's own business nature, the flow analysis, constructs one to adopt what technology the VPN satisfies the demand, if only uses the data service, may adopt the non-connect
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

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.

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

It is recommended that enterprises consider the following five issues before switching to VoIP:
1. Is your network wiring qualified?
The level of enterprise internal network cabling is very important. We recommend that you use a CAT-5e (100 M) or CAT-6 (1G) network cable for optimal voice quality because network speech requires additional bandwidth to improve voice quality. According to experience, most problems with many
Part 3rd Infrastructure attacks
Set the wireless card to "listening" status to identify which wireless network is active. With the help of "Aircrack-ng"-a wireless Network monitoring toolkit, the ability to intercept the 802.11 wireless network raw transmission data, especially good at intercepting the WEP initialization vector, to crack the WEP key.

We also talked about the SIP Protocol and related SIP protocol stack. In this paper, we propose a software structure and design implementation scheme of the software telephone based on the SIP protocol. this solution is based on the embedded Windows CE platform. The middleware uses the Open-Source SIP protocol stack oSIP/eXosip, through protocol stack transplantation and application development on the protocol stack, the SIP software phone is implemented. the test results show that the software
