Getting Yourself Acquainted With SIP Trunking

You must have already heard of SIP Trunking but I suppose you are not yet aware of this particular acronym. SIP stands for Session Initiation Protocol and when we say SIP Trunking, we mean service connections that are generally offered by Internet Telephony Service Providers. The concept is to give connections from the company to the PBX with the use of internet servers – the result is VoIP.

Say for example, if an employee dials a particular number and does a call that passes through traditional telephoning system of PSTN, the SIP trunking will designate the company’s IP to a PSTN number that is considered the closest to the dialed number. This way, the employee who is making the call will only appear to be calling just within the neighborhood or town. This will significantly lessen the long distance charges to the company. This kind of telephone system also works the other ay around in the sense that it can give local PSTN numbers to customers to call wherever what part of the country they may be. But the most interesting part is that when these customers dialed these local numbers, their calls will be automatically directed to the PBX. This will give the customers hassle-free and affordable calls.

What is also interesting about SIP Trunking is that it reduces the use of many physical connections and that the calls that are handled by SIP trunks are not limited so you can call as long as you want. But since the calls that usually pass though SIP trunks, the calls are determined by their bandwidth. This is the reason why companies make sure that they prevent too much traffic (often caused by simultaneous calls) and they give a solution to this by buying more than one SIP Trunk. When you want to get an SIP Trunking service, you can get it from ISP or ITSP providers and depending on the kind of company you have, you can choose the one that works best for your type. It is also worth to see DS3 line, one of the most popular communication solution.
