Answer the call for next-generation voice services

For decades, fixed phone line systems were the obvious choice for voice services. But that was then.

Today, businesses are growing, moving faster and operating in more places than ever. Which means fixed phone lines just don’t make sense anymore. Not only are they expensive to support – they weren’t designed to handle today’s distributed workforces. 

To compete, businesses of all sizes need better solutions. Ones that are both reliable and flexible. Not to mention designed to meet their communication needs of today – not 20 years ago.

That’s why forward-thinking businesses are streamlining their telephone connectivity with Session Initiation Protocol (SIP) Trunking from Acronym.

Why it matters

If you have a traditional phone system and teams working in multiple offices, you could be paying twice as much as necessary for voice connectivity. You might also be paying for services you don’t even use anymore. Which, obviously, isn’t good for business. That’s why when you upgrade to SIP Trunking, you’re doing more than improving your tech stack. Your business gets the flexibility it needs to scale voice sessions up or down, meaning you only pay for what you need. Plus, you save up to 50% of the costs typically needed to maintain multiple legacy communication circuits.

How it works

Think of SIP Trunking as a telephone line that’s embedded in the internet connection you already have. Rather than paying for an entirely separate network to make phone calls through business lines, SIP Trunking leverages your existing Acronym data connection to carry both voice and data on the same network.

Acronym makes the transition to SIP easy. You already have the infrastructure you need for SIP compatibility; we simply come in and set it up. You also have the option of connecting your phone system (i.e. Private Branch Exchange or PBX) directly to our Acronym network with minimal configuration changes. The benefit of our network is twofold: it offers higher call quality and more security, with fewer routing challenges associated with the public internet.

Let's compare

Fixed-line phone systems are complex and expensive to support. Each office location requires its own voice and data service, as well as a PBX. Larger offices also need their own phone systems, adding to the complexity and cost.

With SIP, voice is an application that operates on the existing data network. Businesses can use one, centralized phone system for all employees and locations. This reduces costs and complexity, and allows a consistent voice experience, wherever employees are working.
