SIP Trunking – Understanding The Technology
Session Initiation Protocol Trunking, otherwise known as SIP Trunking, is a technology of communications connection service given by certain Internet-related providers like ITSP and ISP.

The concept for this connection is to attach the telephone system of a certain company to its Private Branch Exchange (PBX) using internet servers, which then allows Voice Over Internet Protocol (VoIP).
For example, one employee of a SIP provided company calls a regular phone number. This regular phone number is called a PSTN number or Public Switched Telephone Network number. The SIP Trunking service will modify the IP of the caller to a PSTN number close to the callee.
Through this, the employee will appear as if they are making a call under the same network. This will then improve the quality of communication services for the call and the company might even be spared the long distance charges. And, this type of setting can actually be the other way around as well. Let’s say that a particular SIP provided company gives out local PSTN numbers for consumers in different parts of the country.
But instead of going through operators and bothersome call transfer, the costumers who dial these local numbers will automatically be forwarded directly to the company’s PBX. This kind of calling service is far more convenient for costumers and better for the company’s reputation as well.
SIP Trunking is really practical as it eliminates the use of so many telephone wirings. Also, SIP trunks can actually handle multiple phone calls at the same time. But there are still chances that too much calls can produce heavy bandwidth traffic, which leads to blockage on the company’s networking. So what most companies do is that they simply but multiple trunks to prevent such kind of problem from happening.
Again, SIP Trunking can be acquired from an ISP or ITSP provider, so it depends on the company whichever they choose.
