Phone Systems - PBX with SIP Trunks

PBX systems are generally used within an enterprise for internal communications; however businesses like yours need to stay connected with clients and that is where sip trunks come in. The system allows your existing traditional PBX or Cloud PBX system to communicate outside the borders of your enterprise to Public Switch Telephone Networks (PSTN) or regular telephones and mobiles.

Sip trunking works by allowing voice data to be transmitted over an enterprise's internet connection through an IP network then through the service provider's cloud network where it will allow connection to PSTN and vice versa for incoming calls. The system has three essential components to work properly:

An IP based PBX which connects all end points of an IP network and has Sip trunking capabilities. A SIP traffic manager device often referred to as border element which is essential in transferring calls from in and out of PSTN. The ITSP or simply the service provider that will allow connection between your PBX and outside phone systems.

Advantages of Sip Trunks

Not only you can maximise your IP-based PBX system, SIP trunks can benefit your company in a number of ways. Firstly, costs are very modest the system does not require any expensive gateway units needed for traditional phone systems and line packages are a mile cheaper! Secondly, you can say goodbye to additional expenses of all the geeky stuff of traditional phones like ISDN, BRIs, PRIs and line rentals! Thirdly, you will only pay for what you use, traditional business phone systems are powered by PRI (Primary Rate Interface) which is normally consist of 23 channels, in sip trunks channels can be purchased individually depending on what you need!
