Session Initiation Protocol (SIP) TrunksCommunication Systems

Turn your old hardware into new tech with Session Initiation Protocol (SIP) trunks

What is a SIP Trunk?

Session Initiation Protocol technology has been around since the late 1990s, and with ongoing changes to the way we communicate, has become a key consideration for organisations across Australia and the world.

What is Session Initiation Protocol (SIP)?

Each instance of a phone, video or instant message chat is overarchingly considered as its own session. The establishment of the session itself is where the initiation part of the name comes into play, and protocol is the set of rules and procedures that devices use to stay connected.

Session Initiation Protocol, usually shortened to SIP, is all-encompassing of the above – a type of communication system that allows organisations and staff to activate real-time communication sessions. Think audio, video and instant messaging chats that use a digital phone line over a high-speed internet connection, rather than a physical telephone line.

What is a SIP trunk?

When you read about SIP, you’ll likely come across the term ‘SIP trunks’. Just a second ago, we said that Session Initiation Protocol uses a digital phone line, and that’s basically what a SIP trunk is. A SIP trunk allows you to utilise your existing equipment, while still making the transition to voice over internet protocol (or VoIP).

Our IAX and SIP trunks use your existing internet connection to replace the old telephone lines (such as ISDN or PSTN lines) that physically run into your business (we know… so many acronyms!). This process enhances the capability of your current phone system, and reduces your call costs significantly.

Xenex Systems provides SIP trunks for existing private branch exchange (PBX) phone systems.

What are the benefits of SIP?

  • Save capital while going global

    Moving to a hosted VoIP system that uses Session Initiation Protocol (SIP) technology reduces capital expenditure while lowering ongoing call costs to local and international numbers. Plus, you can set up a local number for your customers to use wherever they are in the world.

  • Get carrier-grade reliability

    Xenex Systems uses high-grade servers to get our clients the crispest call quality via SIP trunks and technology in Australia and across the globe.

  • Scale your solution

    SIP as a cloud-based solution, which means it’s easy to increase the number of users or cater for an increase in inbound calls as your business expands - without the need for the capital and equipment costs associated with onsite PBX systems!

  • Use multiple platforms

    Desktop soft-phone, mobile applications and physical phone systems can all be connected to a single number through SIP trunks and SIP technology for ease of management and consistency of access.

  • Harness the power of reporting

    Data from Session Initiation Protocol (SIP) can be captured and processed to generate reports, monitoring anything from live call logs and average call times, to answered and abandoned calls. With the data in your hands, you’ll know your weak spots inside and out.
