A business phone system is a telephone system that combines multiple phone lines and supports additional telephony features such as call handling, call transfers, conference calling, voicemail, and more. 

There are many different types of phones, each with its pros and cons, ranging from traditional PBX systems to cloud-based internet telephony (VoIP) solutions.

  • Traditional phone systemsPrivate branch exchange (PBX) phone systems are traditional landline systems that work over business phone lines and often use on-premises PBX servers.  Systems like this incur expensive upfront costs and come with ongoing maintenance charges. For small businesses, that could mean taking out hefty business loans. 
  • Self-hosted VoIP phone system (IP-PBX)
    A self-hosted VoIP (voice over internet protocol) system connects calls over an internet connection. But the communications server can be located on-premises. Self-hosted VoIP only works with SIP phones. This is very similar to a traditional PBX but tends to be much cheaper. 
  • Cloud PBX phone systemCloud-based VoIP systems use apps or internet browsers to make and take incoming calls over the internet. This is the most flexible business phone model.  VoIP phones allow you to start video conference calls from all mobile devices (iOS and Android included). Thanks to the cloud phone system infrastructure, this is a much more cost-effective option.

A business VoIP phone solution like RingCentral’s offers virtual phone systems and can be purchased for a scalable monthly fee with flexible pricing.

On top of the software itself, this includes business phone installation, maintenance, customer support, and various integrations with call center software, management software, CRMs, accounting software, and POS systems.  Lines can be easily added or repurposed at any time, and there’s no need for expensive, bulky hardware.

What is a multi-line phone system?

Multi-line systems allow a single phone to host multiple phone numbers. This is a great option for startups and small business owners who want to use their personal cell phones for business calls but don’t want to sacrifice professionalism. 

With this type of office phone system, users can accept and make calls by pressing a dedicated key to select the appropriate business line. 

Not every business needs a designated in-house PBX system. A cloud-based multi-line option offers the ideal balance by providing businesses with advanced calling that handles calls to multiple numbers based on set VoIP calling rules.

Step 2: Set up IP phones

Next, you’re going to need to set up your IP desk phones. If you want them, of course. 

Attach your handset to the base of your IP phone using the cord provided. Plug one end of your ethernet cable into your phone’s WAN port and the other end into your router or internet jack.Top-tip:If you don’t have a router or internet jack available, you can connect the LAN port on your IP phone directly to your PC.

Step 3: Transfer your existing toll-free number

After purchasing your business phone, you’ll be provided with temporary business phone numbers. 

If you have an existing toll-free phone number or vanity number that you wish to keep, you can port this to your new RingCentral business phone.

It’s time to personalize your business phone system functionality. Each business is different, and you’ll need to tweak your settings accordingly. 

With RingCentral, administrators can change and set up business phone system settings and assign users and extensions according to their own specifications. Each user will be able to change their voicemail greetings and hold music and adjust call handling rules for individual extensions.
