Virtual PBX
If your business phone system is inflexible, expensive, and requires on-site maintenance, it may be time to switch from a traditional on-premises PBX system to a virtual phone system or more versatile solution. Book a product tour to see how easy it is to make phone calls, send SMS/MMS messages, and even have video meetings with Dialpad's AI-powered communications platform!

For most businesses that are considering a virtual PBX phone system, their main must-haves are cost-effectiveness, flexibility, and ease of use.
But there's actually an even better option that lets you not only manage incoming calls, but also handle other communication channels—from a desktop or mobile app (aka. a softphone). More on that in a bit. For now, let's have a quick refresher on what virtual PBX is.
What is virtual PBX?
Virtual PBX, sometimes also referred to as cloud PBX, is a type of phone system that's a newer alternative to traditional PBX (Private Branch Exchange) systems. Rather than relying on physical hardware, switchboards, and landline connectivity, virtual PBX lets you make phone calls through the Internet.

How does virtual PBX software work?
Virtual PBX uses technology such as cloud-based software and Voice over Internet Protocol (VoIP) to give you the same functionality as traditional PBX phone systems. While traditional phone systems send analog data through copper wiring and landlines, virtual PBX software sends that voice data digitally through the Internet.
Today, though, these types of cloud phone systems have evolved even more, and you're likely to hear about "UCaaS" or "unified communications platforms" instead of just cloud or VoIP phone systems. The difference: UCaaS and unified communications platforms don't just give you phone calls like PBX phone systems do—they also let you communicate in other ways, like through instant or SMS/MMS messaging, and also video conference calls.
For example, that's exactly what Dialpad gives you (in addition to all the usual business phone features you'd expect, like an auto attendant and IVR (interactive voice response):

A few virtual PBX hosting comparisons
Virtual PBX vs. traditional PBX
The main difference between virtual PBX and traditional PBX is that virtual PBX systems use the Internet, while traditional PBX uses on-premises hardware and landlines.
Both virtual PBX and traditional PBX typically have standard PBX features like call forwarding, conferencing, and voicemail.
Virtual PBX vs. IP-PBX
After traditional, analog PBX systems came IP-PBX phone systems, which was a first step in creating phone systems that worked over the Internet. Learn more about IP-PBX and how it compares to other types of PBX and VoIP phone systems.
Virtual PBX vs. hosted PBX
"Virtual PBX" is sometimes used synonymously with "hosted PBX," and essentially what "hosted" means is simply that your phone system is managed by a third party provider somewhere else—not in your own office. Your hosted PBX vendor likely has its own data centers and provides all the IP phones, hardware, software, maintenance, security, and upgrades you need.

Call forwarding
Have you noticed that a lot of call forwarding features can be over-complicated and tricky to use? One minute you’re trying to forward a call to your colleague, the next you realize that an important customer is no longer on the phone at all.
A UCaaS or collaboration platform should let you easily set up and change your call forwarding settings. With Dialpad, for example, you can add up to five call forwarding numbers to your system and make any changes whenever you feel like it via your dashboard. No unnecessary complications.
Auto attendant
Why should you handle multiple calls about simple subjects like opening hours when you can have an auto attendant do it for you?
Today's communications platforms should come with an auto attendant feature that can provide basic information and answers to callers, and can also route calls to the right department for you.
Call queue
Call queuing allows larger companies with call center teams to handle large volumes of calls with ease. If you get more incoming calls than you have available agents, queuing places your callers into a queue to be directed to an agent when one becomes available. You can thus deal with call spikes without affecting the customer experience.

Virtual PBX FAQs
Virtual PBXs are cloud-hosted using off-site servers which belong to your telecommunications provider. On-premises PBX systems, on the other hand, rely on hardware and infrastructure at your own workplace.
With a traditional PBX landline phone system, you'll need to get your provider to help with setup and also need to purchase hardware for the office.
Setting up a UCaaS platform or virtual PBX phone system, on the other hand, is usually much faster and easier. All you need to do is sign up for a subscription plan and download the app to connect your phones, PCs, and other devices to the platform. Some providers, like Dialpad, also help you port over your original phone numbers.
New virtual PBX systems tends to be very versatile. They can connect with mobile devices, desk phones, landlines, and any computers that your company already has.
Virtual PBX is an internet-based system which allows you to conduct, route, and manage telephone calls via the internet.
Modern businesses will generally find VoIP solutions and UCaaS platforms more scalable, flexible, and cost-effective compared to PBX or landline phones.
If you're just looking for a system that lets you make phone calls over the internet, a VoIP-based solution may be good enough. If you need team messaging, SMS/MMS messaging, and video conferencing, then a UCaaS platform would be better. Cost-wise, some UCaaS platforms are comparable or even cheaper than VoIP and PBX systems, so in most cases, it makes sense for businesses to go with the more robust UCaaS option.
