are for this reason). However, there are also many enterprise accounts out of high value Return Considerations: 41% of companies say they can use VoIP to build an all-in-one communication platform, 36% of companies want to increase collaboration by integrating voice and data sharing, video conferencing, or online notification Technology.
For whatever reason, VoIP will be a direction for enterprise applications. In the near future, it will become the main way for most enterprises to communicate.
In the process of learning the SIP protocol, we need to be clear about a concept, that is, the concept of SIP relay. In order to help you better understand this aspect, we use a comparison between Chinese and English translations to help you understand this aspect. The specific information is as follows:
A sip Trunk is a logical connection between an ip pbx and a Service Provider's application servers that allows voice over IP traffic to be exchanged
PBX. The phones on the network use the existing architecture to call VoIP phones. Many large enterprises choose to replace PBX with ip pbx without changing the installed internal telephone lines, saving the company the cost of replacing all telephones. Citel, Intel, and other companies provide such phone gateways.

When talking about open source IP-PBX, people familiar with this field probably know
AsteriskThis famous open-source ippbx. There are many technical documents about asterisk. However, what I want to introduce here is another ippbx solution, which is also an open-source system-
Sipxecs. I checked Chinese information and introduction about sipxecs through Google and found that there were not many, obviously it was no longer popular with asterisk. Howeve
Recently, various attacks against VoIP voice gateway devices have frequently occurred, causing many troubles and economic losses to customers. In order to further prevent the VOIP Voice Gateway from being compromised by a network attack or attack, the network technology provides several preventive measures for the security of the voice gateway device, ask the customer to take measures to prevent the security of the voice gateway device.

Pukot solid-state hard disk in the industry has a very good reputation, belong to the first-line SSD brand camp. Today for you to recommend the first 120GB-128GB SSD is today recommended 6 of the most expensive products, but the comprehensive performance of this product is undoubtedly the most prominent.
This Pukot px-128m6s solid-state drive is slightly more expensive than other products, but sales and Word-of-mouth are still very goo
provides both voice and data interfaces. If you have an integrated access device, make sure it can be upgraded to a full-featured router with new software before changing it. The "VoIP" that appears here is only the data-based voice data between the external connections of the PBX.
For enterprises with more than one site, a good start is to replace the current direct connection telephone line with VoIP between different sites. In this step, you do no
Asterisk is an open source PBX system and it is difficult to find a detailed description of the asterisk kernel system in public information. Therefore, it is necessary to write a core framework of the description of the document as an internal training document, learn from each other to improve.
This paper mainly describes the asterisk kernel from three levels, that is, asterisk kernel module, kernel boot process and basic call flow.
First, asterisk
The asterisk core handles these items internally:
PBX switching-The essence of communication, of course, is a private branch exchange switching system, connecting calltogether between varous users and automatic tasks. The switching core transparently connects callers arriving on various hardware and software interfaces.
Application launcher-Launches applications which perform services for uses, such as voicemail, file playback, and directory listing.
For H3C unified communication, we have briefly introduced it in the previous article. Now we will introduce its solution features in depth. Of course, we can also see that these are also the characteristics of the Unified Communication System. In the H3C Unified Communication solution, how do they use this technology to make it more stable and more practical for enterprises?
H3C Unified Communication has a hierarchical architecture and open and standard IP technology and interface protocols. It
The Programmable switch, also known as PBX (private branch exchange), is the main channel and bridge between the call center and the outside world.Programmable switchProvides external interface with the local telephone Relay (generally E1 digital relay), and internal interface with the agent representing the phone and automatic voice response device.

Looking back at the development process of the Unified Communication Platform, what do we feel? I just think that the progress of science and technology is confusing. Who once thought that the old beacon was a video exchange? Who once thought that the original fast whip, just for a letter, now a bunch of waves can pass your mind.
Although the Unified Communication Platform has entered our field of view for a certain period of time, what is unified communication. Some people say that Unified comm

Integrated Access Device (IAD)
