In the world of VoIP (Voice over Internet Protocol) systems, what does SIP Trunking mean? SIP means “Session Initiation Protocol.” SIP is the standard by which all voice communication takes place in a VoIP system. SIP stands for “Session Initiation Protocol.”

So, what does SIP Trunking mean and how does it help VoIP communications? SIP means “Session Initiation Protocol.” SIP is what allows telephone calls to take place over an Internet network. SIP is a way by which businesses can use their existing broadband internet connection to communicate over the telephone generally by voice as well as video. SIP trunks are used primarily by businesses that have branches all over the country or even the world.

A SIP Trunk is nothing more than a simple phone that receives calls and forward the calls to the correct destination. The “destination” in this scenario can be a local number or it can be another number that the user chooses. For example, if a user calls a local business, the “local” number may simply be the branch office. If that business was to implement SIP trunks, it could route the call to the branch office and thereby save money by not having to provide telephone service to every location that might potentially receive a call.

As an example of how SIP works, consider that Freeswitching is a form of VoIP where the hosted PBX allows users to place their own telephone system inside of an existing PBX. The hosted PBX includes everything needed to enable voice calls to be placed and received, including a feature called “freeswitch.” With free switch, the host system will detect a new call and switch to accommodate the call. If no free switch entry is made, the call will be dropped and the caller will have to dial an answering machine or move to another number.

The benefit to using a free-switch instead of a standard PBX is that it enables the hosted system to be able to handle voicemails, inbound calls, and calls from multiple phone lines. As an office phone system, it is very difficult for a single employee to answer each call and then make a choice as to which call to accept. It also is not cost effective for an office phone system to handle all calls. However, with a free-switch, an employee can place a call anywhere, anytime, and the same call will be handled by multiple telephone systems from different providers.

What does SIP Trunking mean to you? In order for SIP to work, a group of IP phones are connected through a trunk system. These IP phones belong to a group, which may be local, state, city, or region. In order for the group of IP phones to talk to each other, they must have been assigned an IP number. The number assigned to each phone belongs to a certain port number.

So, what does SIP trunks mean and how does it work? Essentially, it provides for voice data to travel between IP phones in a data trunk, so that the voice data does not get corrupted along the way. A session border is essentially a demarcation of that boundary. An IP session border is essential for proper voice data reception; however, demarcations are usually done at the layer of datasharp integrated communications (DIC).

What does sip trunking mean for companies who want to implement a Voice over Internet Protocol (VoIP) application for their business? For one thing, it can save a huge amount of money. Saving money and time means having an efficient communication system which is also highly reliable, secure, scalable, and cost effective. To achieve this, most companies will need to begin planning for an implementation of an agile business VoIP application using an IaaS solution like Metaphone.
