A complete guide to SIP numbers and how to use them.

Looking for a new business phone number or interested in upgrading your current phone system? Enter: SIP numbers.

Everyone – from small businesses to large corporations – can use SIP to build a more effective phone system. In this article, we’ll cover the basics of these numbers, the benefits, use cases, how to get this solution, and more. This way, you know if this solution is right for your needs.

In this guide, we’ll cover:

What Are SIP Numbers and How do they Differ from Traditional Ones?

SIP numbers use IP telephony technology to deliver voice calls between two or more parties over a network. In other words, these cloud-based phone numbers allow your business to make and receive calls through an internet connection.

So, how are SIP numbers different from traditional ones?

Instead of using physical phone lines – like traditional numbers do – SIP numbers use digital pathways to transmit voice. Although these phone numbers differ from traditional ones, they look the same. Both number types feature the same numerals and formatting. And this is why you’re able to port your existing phone number to a new cloud-based provider.

Other names for this service include:

  • SIP lines
  • SIP trunks
  • SIP addresses
  • VoIP numbers
  • Cloud phone numbers
  • Virtual numbers and so on.

How Do These Numbers Work?

SIP stands for Session Initiation Protocol. It’s a signaling protocol that powers SIP numbers and makes real-time IP-based calling possible.

When you place a call, this technology breaks down your voice into data packets and sends them to the receiver via a network connection. Once these packets arrive at your desired destination, they reassemble into voice. And this process happens in a matter of seconds for a seamless calling experience.

For a more in-depth look at how this technology works, check out our guide on how SIP trunking works.

Benefits of SIP Numbers

From its cost-effectiveness to its scalability, SIP has no shortage of benefits for your business. Let’s take a closer look.

• Affordability

SIP numbers are one of the most affordable communication solutions on the market, especially when compared to traditional numbers. This is because they use the internet, allowing you to make local, long-distance, and international calls at inexpensive rates.

• Reliable High-Quality Calls

These phone numbers do not rely on physical landlines. This means that you not only experience higher call quality but also improved reliability.

For instance — If a call goes unanswered at its initial destination, this technology has failover capabilities that automatically reroute calls from one location to another. So with SIP’s built-in redundancy, you can rest assured that you’ll never miss a call, even during a power outage.

• Global Coverage

Global SIP services allow you to connect with prospects and customers around the world from your current headquarters. With Global Call Forwarding, you gain access to over 160 countries worldwide, making it easy to expand your business to new markets with minimal risk.

• PBX-Compatible

SIP numbers are compatible with most existing PBX systems. Simply plug this service into your current PBX to increase functionality and modernize your legacy business communication, without replacing your entire setup.

• Mobility & Flexibility

With a cloud-based SIP number, you’re not tied to one geographic location or device. In other words, you can place calls using any IP-enabled device and from anywhere in the world.

• Advanced Communication Tools

Most providers offer users access to a suite of advanced call features that boost your system’s performance. Some popular features include international call forwarding, caller ID management, softphones, IVR, and more.

• Scalability

You can modify and scale your SIP service as needed. Add, manage, or remove lines and users based on your business’ growth.

How to Use SIP Numbers [4 Use Cases]

Businesses of all sizes and industries can use SIP numbers to improve their service and drive growth. For a better idea of how your teams can use this tech, here are 4 examples of popular use cases:

1. Provide 24/7 customer support

With access to communication features only available through the cloud, you can offer 24/7 support to customers around the world. Simply set up location-based and time-based routing strategies or adopt a Follow the Sun model. So, when customers call your main SIP phone number, your system automatically routes them to the best available location.

2. Expand to new global markets

SIP numbers provide you with an easy and cost-effective way to enter new markets and expand globally without relocating your teams or offices. Get SIP phone numbers for each of your target countries and then forward incoming calls to your main headquarters. This allows you to access new customer bases with minimal risk while keeping overhead costs low.

3. Connect local, remote, and international teams

Since this technology provides mobility, flexibility, and centralized call management, you can use these numbers to connect teams across multiple locations (including remote and distributed employees) and encourage collaboration. Make sure to select a provider that delivers all your desired features and services in a single platform. Or, use APIs and integrations instead to develop your current system.

4. Localize your business

With a local phone number, your business can easily establish a local presence in target markets and boost connection rates with local customers. Get SIP numbers with recognizable area codes or use caller ID features to display a local number.

The great thing about cloud phone numbers is that they can be used in a number of ways because they are adaptable to your specific needs and business goals.

While waiting, you can pass the time by making sure your setup meets the basic requirements to power SIP.

All you need to get started is:
