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.

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:

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

In iOS background execution is what this article describes, and most applications go into a paused state shortly after entering the background state. In this state, the application does not execute any code, and it is possible to remove it from memory at any time.

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
is complete, the main task of IoT is to validate the new features and new standard versions (such as 3GPP R4) as the manufacturer's software version is upgraded.

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
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.

[Q]: What is shadow memory?[A]: In the current computer system, shadow memory is in the UMA (upper memory area; the traditional memory is more than kb to 1 Mbit/s) "Inside" (part of it ); in this Uma, it can be divided into 6 segments (64kb/each) and total 384kb.

memory (Highmem) method. on IA-32 Systems, the amount of physical memory that can be directly managed is no more than 896MB. Memory exceeding this value can only be addressed through high-end memory "Why is 896?! Two constraints are met: 1. Directly mapped memory as much as 2. The remaining virtual address space is sufficient to manage excess memory ".Main: 1. Before the kernel uses high-end memory, it must be mapped to the kernel virtual address space using the KMAP and KUNMAP functions, which
