the user receiving the service will be divided by the Tom-skype and the service provider by 3:7.

I began to study the VOIP/SIP agreement from 09, open source project also saw a few, the earliest Pjsip 05 began to push the time, began to pay attention to, also in their own winmobile project used. Later also saw Sipdroid,imsdroid (Doubango), Linphone,csipsimple (PJSIP).I think the best advantage of Linphone and Csipsimple,linphone is the full platform support, Android,ios,winphone,windows,linux,mac osx,web all support, but the quality is still unde
contents of the call. in a voice call, this is known as speech, and that's the media part. before being able to send and receive media, the parties must negotiate the media properties. why do you need media negotiation? For voice, the reason is that there are already different ways to represent the contents and compress it. this is similar to having several formats to play sound on your desktop (WAV, MP3 and Ogg), but in this case, the devices choose the format for the conversation. furthermore
We all know that our program runs in the background for 10 minutes and stops after 10 minutes. But like real-time positioning, playing audio, and VoIP, we need to keep running in the background.

We know that IOS can get a maximum execution time of 600 seconds after enabling background tasks. How do some apps that need to be downloaded in the background or kept connected to the server exceed the limit of 600 seconds? For example, Netease open classes can be used for continuous download in the background, and Youku can also continue caching in the background. How does this happen? Generally, to enable Ios to run in the background for a long time, you need to declare
Compared with building intercom, the network phone number can be said to have been in our daily use for a short time.
Generally speaking, a network phone is a system for voice communication in a computer network with IP as the network layer protocol. The technology used is collectively referred to as VoIP (Voiceover IP ), that is, the network is used for voice transmission. Technically speaking, the IP network telephone is the result of the integratio
About every 10 years or so, there will be a new technology that promises to change the way SMB businesses operate. The purpose of presenting this fact is not to explain whether these new technologies can help enterprises, but to explore how to integrate these new technologies into existing business processes and systems. Obviously, integrated voice and data networks are also a new technology that can use Unified Communication to provide IP voice VoIP)
recently, the SIP protocol was used, so we looked for two open source projects to compare, Linphone and Pjsip, and finally chose Pjsip this open source protocol stack for development.The main reasons are as follows (for personal reference only):1, Linphone code structure than Pjsip clear, pjsip in Windows more convenient debugging ;2, Linphone after the update does not use Osip as a protocol stack, instead of self-written BELLE_SIP,PJSIP protocol stack is maintained, and has been stable ;3, Pjsi

On the PBX or local switch side, a small amount of power is not fully converted and returns along the original path, forming an echo. If the caller is not far from the PBX or vswitch, the echo will return very quickly and the Speaker cannot hear it. In this case, it does not matter. However, when the response time exceeds 10 ms, the human ears can hear the echo. In order to prevent echo, echo cancellation technology is

In a recent webcast, we discussed performance management and what to view when you check your statistics. The worst case is to use network utilization as a measure of network health. There are other more valuable statistics. Utilization is very important, but it is only a small part of the network health status.
There are two problems with utilization. First, it is almost impossible to determine when the workstation is in use. Even if a person is sitting at his desk, he may be on the phone and d
