Important Qualities of SIP Trunk Providers

sip trunk providersWhen you’re running a large or mid-sized business, you’re always looking for ways to lower costs and increase productivity. Which is why SIP trunking is growing quickly in popularity.

In fact, experts are forecasting that the SIP trunk global market will reach $8 billion in 2018. That’s because using a SIP trunk means lower costs along with increased reliability.

90% of SIP trunk users report that they are satisfied with the audio quality.

But what exactly is SIP trunking? And what qualities should a business look for in SIP trunk providers?

To help you set your standards higher than your competition, we’re sharing with you the best qualities SIP trunk providers should have.

What Can SIP Trunk Providers Do For Your Business?

SIP Trunking (Session Initiation Protocol) is a method by which businesses operate their phone systems using an internet connection rather than a traditional phone line. There are several benefits to switching from a traditional phone line to a SIP trunk.

Savings is one of SIP trunking’s best benefits but far from the only one. By switching to a SIP provider you’ll save money by only paying for the number of lines you need.

You’ll also save a lot of money by only paying for the minutes your employees actually use. Often company’s see a savings of 60-80% from their current phone bills.

This allows your company more efficiently use communications costs and also reduce or eliminate wasted resources. So it makes sense to look into making the switch.

What Qualities Should SIP Trunk Providers Have?

Running a business is hard work. Which means you want to choose the right SIP provider company the first time. Otherwise, you’re wasting your valuable resources.

So here’s what the best SIP providers should be providing to your company.


You wouldn’t hire and retain an unreliable employee, so why would you pay for a service that keeps breaking down? Especially when that service is a large part of how you communicate with your customers.

Without a reliable phone service, your customers can’t rely on you. While most claim to have a 99.9% uptime, that’s not always the case.

Here’s what to look for.

Direct Interconnects with Tier 1 Providers

Not all SIP trunk providers work directly with tier 1 providers. For those providers that do, when service goes down, it’s usually a quick fix.

For those providers who choose to purchase their connections and routes from intermediate carriers, when a failure occurs, it takes much longer to pinpoint the source of the problem. That means you’re stuck waiting until they figure it out.

Fully Redundant Call Routing and Failover Provisions

Mother Nature doesn’t always play fair. When a natural disaster or technical outage occurs, you’ll want a provider offering fully redundant call routing and failover provisions.

That way, if the worst does happen and the network goes down, you still won’t miss a customer call.

The Ability to Easily Scale Your Business

Most businesses are in the business of growing. Which means working with companies that allow you to easily scale their product according to your current needs.

The right SIP trunk providers will always make it easy for you to add or remove lines as needed. Even better, those changes can easily be made within 24-48 hours of your request.

Remember that as your provider adds or removes lines, you may need to adjust the amount of bandwidth, too. However, a good provider will help you plan for those needs.


SIP trunking services are run over the Internet, which means security is definitely a major concern. Ask potential SIP trunk providers about what security measures they take to prevent security breaches and toll fraud.

If the SIP provider is taking the right measures, they will be taking all or at least most of the following steps:

Call Barring

Call barring allows you to block or modify access to certain nations or destinations. Since most toll fraud occurs when hackers are making expensive long-distance calls over your cloud-based phone system.

With the call barring feature, you’ll have real-time control over your traffic, allowing you to protect your company against potential fraud.

Credit Limits

Credit limits allow you to prevent international toll fraud. If a hacker breaks into your system and is placing expensive and fraudulent calls, having a credit limit means your system will disconnect and block further traffic.

24/7 Anti-Fraud Monitoring

Anti-fraud monitoring is a must-have these days. The best SIP trunk providers are already detecting fraudulent VoIP activity.

Which means at the first sign of any trouble, they’ll take action to prevent further issues.

Customer Support

Sometimes unexpected problems arise and you’ll need to reach your provider. And any business knows that problems can come up just as easily at 2 am as they can at 2 pm.

So make sure your provider is available 24/7 and has a team of professionals who can easily and quickly answer your questions and resolve any problems.


Not all SIP trunk providers are the same. They don’t all offer the same options.

But not all companies are the same, either. You may want to choose options like:

  • Pay as You Go Pricing
  • Voice and SMS on the same number
  • No contracts
  • Unlimited nationwide calling

However, there’s a lot more to choosing the right SIP trunk provider company. They also offer calling features that can help your business grow.

So you may want to choose a provider company that can offer:

  • Account Codes which are a dialed code that can track calls.
  • Toll-free calling with IP addresses instead of DID numbers
  • Audio conferencing services
  • Disaster recovery routing in case of emergency
  • Auto attendant which serves as an automatic receptionist for incoming calls
  • Growth reserved numbers for when your company enjoys future growth

SIP trunking definitely has a lot of great features. But don’t take our word for it. 80% of businesses with over 20,000 employees say SIP is very important. 80% of businesses with only 100-500 employees say the exact same thing.

Did you know that most companies realize they are saving 10%-40% from their voice budget?

With numbers like these, it seems like every business will soon be moving their phone lines to a SIP trunk provider. Sign up for a free account to get access to a simple to use SIP trunk solution that makes selling and managing your customers a breeze.
