Explanation of SIP and how it works?

SIP calling eliminates the need for PRI lines. A SIP trunk, a telephone line that uses the SIP protocol, is virtually installed through your internet connection. It then uses this internet connection to connect your PBX to the PSTN, bypassing the PRI line.

Results? You can use call management features like auto attendant, call forwarding, voicemail and more without analog or multiple phone lines.

Benefits of SIP Calling

By now, you know that SIP calling can help you move your company forward. Let's unpack the key benefits of SIP calling and their impact on your business.

1) Cost-effective communication

Think about the size of your current business phone bill. Now imagine paying less than 70% of that. With SIP trunking, that's exactly what you can achieve.

If you're wondering why there's such a big difference in communication costs, here's what a SIP call will do for you:

Unlimited toll-free calls, no per-minute charges

No need for expensive new hardware

Avoid high installation and maintenance costs

There are no service interruptions, so you won't lose business

With SIP calling, you can eliminate worrying about your phone setup costs so you can focus on your customers.

2) Easy scalability

“Okay, costs are going down, but my company is growing. Would I pay as much as before SIP just because of that? ”

This is a valid question. You don't want to change your entire phone system only to be back to square one when you hire more people or expand to a new location.

When you use SIP trunking, everything from phone calls to video conferences happens over the internet. That means you don't have to buy more physical lines just because you need more phone numbers or concurrent calls.

Your SIP provider will help you add more lines, and you can even do it yourself. Easy.

3) Unified communications = flexibility and productivity

When we looked at the differences between PSTN, VoIP, and POTS, we found that companies using unified communications saved up to 115 minutes per day for each user. Almost two hours!

Simple: SIP phone systems help you create a unified virtual presence. Instead of consistently switching between communication channels, you can centralize and synchronize them.

As a result, you'll see better collaboration, productivity, and efficiency. Whether you're in an office of 10 people or have hundreds of employees around the world, everyone can be contacted via the device they already own — their smartphone.

4) Reliable and high quality calls

A physical landline can let you down when you need it most. Power outages, system failures, or bad weather are not things you can plan for.

Poor quality phone calls, or no phone calls at all, are not an option.

Luckily, SIP calling ensures a way to receive calls even in these unpredictable scenarios. This is possible thanks to redundancy, which automatically redirects your calls to another location or an employee's cell phone.

5) Great user experience

Lastly, if you dread having to master new technology and train your employees on it, you can relax.

You can manage everything about your SIP account from a simple interface. Your SIP provider will make sure you are set up and ready to go. You can use it to manage your entire business phone system, such as call routing, extensions, adding phone lines, and more.

This is an easy-to-use way to gain complete control over your entire company communications system.

Who Uses SIP Calling?

Companies with existing on-premises PBX systems, also known as IP PBXs, can leverage their PBX systems to the cloud.

Larger companies may prefer to switch to SIP calling. This can seem especially challenging if they have thousands of employees in different countries or continents. That makes switching to SIP impossible without service disruptions and expensive bills.

But the longer you delay the switch, the more expensive it will be to run your business communications in the long term.

SIP calling lets you:

Collaborate via video chat, messaging, conference calls, & more

Connect with anyone inside or outside your company instantly, regardless of their location or technical setup

Use your device of choice to make important calls by turning your laptop or tablet into a softphone

Integrate all your communication channels

Whether you're looking for small business or enterprise-level phone services, moving your phone calls to the cloud will pay off.

Can I make SIP calls on iPhone and Android?

Yes, you can complete calls using your SIP provider, but with a little extra configuration. Smartphone users can make SIP calls using their phone's settings, or preferably, using a SIP calling app.

For iPhone users, Apple provides developer tools to integrate their calling capabilities into the phone for a seamless and consistent look. This means users who want to use their SIP provider will need a third-party application to make calls from the phone.

For Android users, Google provides users with a built-in setting to register your device with a SIP provider. They also provide a way for developers to create familiar call interfaces that users love.
