better the development of small and medium-sized business services, services must be able to provide multi-line voice and data. To this end, service providers can now provide voice and data transmission services with a copper axis as a physical connection. First, broadband DSL In transport, many technologies support voice and data transfer. When data transmission is optimized, synchronous transmission requires a given address to ensure the quality of long-distance calls. The increasingly soph

When it comes to audio applications, the first thing to think about is the music player. Some players can play streaming media, and some can play local music files. With the evolution of the Android platform, more advanced audio APIs are needed. Fortunately, Google has added this API to support low-latency audio streaming and recording.The Android Audio API offers some advanced features that developers can integrate into their own applications. With these APIs, it is now easier to implement

I have summarized the commonly used ITU speech codec for your reference: 1. g.711: pulse code modulation (PCM) of voice Frequencies Encoding type: Expanded PCMEncoding rate: 64 Kbps Theoretical latency: the time for processing a sample (1/8000 seconds = 0.125 milliseconds ); Sound Quality: Long Distance quality;Advantages: Low algorithm complexity, low compression ratio (CD sound quality> 400 Kbps), minimum codec latency (relative to other technologies)Disadvantage: the occupied bandwidth is hi

VoIP traffic is a fixed time sensor: In a network that provides a service, it is important to ensure the transmission rate. This example shows how to set up one-way to provide the necessary quality of s

Policy-based multi-path Wan The construction of a multi-path Wan can reduce business continuity risks, while avoiding the high cost of building a dedicated-Line Wan and a dedicated-Line Wan. Therefore, enterprises can make full use of cheap and abundant DSL Internet links while effectively utilizing existing WAN resources. The enterprise's reliance on Wan is reaching a record level. Remote access to key business applications grows steadily as enterprises continue to integrate data centers. Howev

What is ip pbx? Ip pbx is a complete set of technologies that can provide telephone calls through the IP data network. All sessions are transmitted over the network in the form of data. This technology not only includes advanced communication functions, but also provides enterprises with extensibility and reliability. Ip pbx can also be connected to a traditional PSTN line through an optional gateway. Therefore, it is easy to upgrade daily business communication to this most advanced voice and d

Session Initiation Protocol (SIP) is the biggest winner in the VoiceCon IP Phone exhibition held this week. Some vendors have announced the launch of SIP-based upgrade products or added support for this security protocol to their existing products.SIP is a single signaling and Event Notification protocol that combines voice, video, and message communication. This Protocol also provides a standard-based approach that enables applications and services to run on platforms provided by different vend

Chinese Internet users have reached 104 million by the end of 2004, 2005 will be expected to break 130 million, of

We plan to add VoIP to our mobile products, which adopt two modes: cellular and wireless LAN cellular/WLAN. When VoIP is used, is the interconnection capability of cellular/WLAN important? If so, which standard is better? At this point, the most important aspect of the standard is the unified memory framework UMA), but it should be clear that the Mobile IP address and UMA are not comparable here. This may n

At the beginning and end of the street, we often see such advertisements at the door of the store: We have installed wireless networks, and laptops can access the Internet directly. Internet access has become the most primitive driving force for setting up wireless networks, which is no exception on campus. According to the data provided by some manufacturers, setting up a complete wireless network will only spend 1/4 of the investment on the wired network, but the effect is obvious: You can ac

The core part of the entire semi-digital building intercom system can be implemented using the Linphone architecture, because the entire Linphone architecture is an open-source network IP videophone system implemented using the RTP + sip architecture.

Mobile App development frameworks are countless, and now there are more and more HTML5-based frameworks. These new-generation development tools allow developers to directly develop mobile applications without having to be proficient in native sdks, Objective-C, Java, and other programming languages.Why is HTML5 so popular with developers?One of the most important reasons why HTML5 is widely used is the emergence of BYOD. The

reason why many people keep their data locally. This gave rise to a hybrid cloud model where locally deployed facilities can work with the public cloud to maintain data storage. However, major cloud providers do not currently support this method. In this form of co-hosting, hosting services can produce higher fees than Amazon Web Services. However, common management provides a LAN network speed for connections between the cloud and the cloud, greatly reducing the number of public cloud instance
