The setting in this is that the PBX or Private Branch Exchange of a company is connected to its telephone system by means of internet servers, and this setup allows VoIP or Voice-over Internet Protocol.
For instance, if a company employee dials a phone number and conducts a call that goes to a traditional telephoning system of Public Switched Telephone Network (PSTN), the SIP Trunking will set the company’s IP to a PSTN number that is the closest to the dialed number.
This action of the Trunking will make it look like the employee is just calling using the same local network. This move will automatically lessen or even completely eliminate the possible long distance charges of phone calls. This is also possible with the opposite situation. For instance, a company that uses SIP Trunking makes use of local PSTN numbers in order to provide communication with costumers in various locations.
But what takes place is that whenever costumers dial any of these local numbers, their calls are automatically forwarded 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. Plus, the calls being handled by SIP trunks are not necessarily limited. 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.
Finally, a company can acquire SIP Trunking from various providers, so there are a lot of service selections to choose from.
