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 also supports IPSec, PPTP, L2TP, and other common VPN passthrough modes. The QoS technology is used to analyze the data and separate the data into multiple layers of data streams, and classify the data according to the importance. Therefore, even when the network is busy, users who use DIR-100 can also enjoy the pleasure of online a

At present, due to different application environments and application requirements, different users have different requirements for broadband routers. For example, SOHO users hope to be simple, stable, and fast, while some small and medium-sized enterprises and Internet cafes th

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.
7th. Remote connection and VoIP attacks1. The public switched telephone network has a mo
An enterprise's boss is enlightened, knowledgeable, and well-managed. From selling lunch boxes to today's three branches in China, he is very cautious in every aspect, to save business costs. The call between two branches and the Headquarters uses the traditional PSTN Telephone Network. The Annual Long call fee occupies a large cost for the company.
One day, I was a little annoyed to be in charge of network management. I said: You see XXX company used its enterprise network to get an IP address.
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
The construction of small office network has become another application hotspot outside Soho office. We have found that the way in which small businesses are built is no longer as traditional and old-fashioned as envisioned, and that more and more small wireless networks are active in small office environments.
This is thanks to the low price of small lines from the product prices, as well as the simplicity of wireless local area network (WLAN), many
