BusinessCo SIP Trunks interface with all major PBXs. They can be connected directly to the PBX and replace any existing telephone lines.
They can be programmed directly into an IP phone and act as a stand alone telephone line with its own telephone number. All you have to do then, is connect the IP phone to an existing broadband service.
You don't need a telephone handset to make SIP Trunks work. There are numerous PC and laptop software applications (softphones) that will turn your computer into a fully functional phone. In a similar way, a SIP Trunk can be programmed into a mobile phone app. This is especially useful when traveling overseas as calls back to Australia are charged at local call rates.
Recent improvements in Australian broadband infrastructure means that an increasing number of businesses can now take full advantage of VoIP technology and make it their primary means of office communications. Business VoIP is fast becoming the replacement technology for traditional business phone lines like PSTN and ISDN.
Traditional business phone lines like PSTN and ISDN require a telephone system and can only be operated from the premises they're installed at. Business VoIP and SIP Trunks change all that. They can be used anywhere in the world as long as you have access to an adequate broadband connection. That’s a powerful advantage and ideal for businesses with multiple offices, remote workers and executives that travel interstate or overseas.
SIP Trunks can be installed on multiple devices, and not just the PBX installed at the business premises. You have a choice between a Softphone (software installed on a PC or laptop), an IP Phone (a phone designed for VoIP technology) or a mobile phone app.
Traditional phone lines rely on the existing copper network that is usually old and prone to faults. If a fault occurs there is no other means of delivering the phone lines. You have to wait until the fault is fixed and that could take days, even weeks.
BusinessCo SIP Trunks come with enterprise grade SLA’s and a service provision level of 99.999%. The most common problem relates to the broadband connection being used. But if that occurs, there are a number of business continuity options like switching to an alternative broadband service or utilising Wireless 4G Broadband.
SIP or Session Initiation Protocol is a means of delivering telephone services over the internet. SIP trunks are the equivalent of business phone lines and use an internet connection to make and receive calls. The technology is more commonly referred to as Business VoIP (voice over internet protocol).
A SIP trunk is allocated a telephone number just like a normal telephone line. This number can either be ported in i.e. transferred from another type of service like a PSTN line, or a new number is allocated.
When a call is made using business VoIP, it travels via the internet to the IP Telephone Service Provider, which it turn delivers the call to the destination. That destination can be any type of telephone service including PSTN, ISDN, mobile phones or another SIP trunk.
The reverse also applies. When a call is made to the SIP trunk number, it travels to the IP Telephone Service Provider via whatever technology is being used i.e. pstn, isdn, mobile, etc., and is then delivered via the internet to the destination.
Business SIP trunks can be taken anywhere and are not restricted to geographical locations. You can take your IP phone or a soft phone (software loaded onto a laptop or smart device) anywhere in the world and as long as you can access an adequate broadband connection, it'll work like it would at the business premises. There are no more challenges with local exchanges, number portability and the need for telephone lines to be physically installed at the premises.
