Comparing an IP PBX to a Virtual PBX

Businesses across the world have started realizing the benefits of innovation offerings like a virtual PBX. However, there are still some firms that remain reluctant to say “yes” to the technology due to concerns related to the security and reliability of VoIP networks.

Looking closer at two business VoIP services, there is the option for an on-premises IP PBX with a SIP trunk as well as virtual PBX service. If a business wants to manage their office phone system as an in-house operation, they can choose a hardware or software IP PBX which they maintain themselves that comes complete with a SIP trunking service from a business VoIP provider.

Hosted or virtual PBXs are operated and provided entirely by a VoIP service provider like Nextiva. The customer accesses and utilizes the hosted PBX remotely through a cloud platform. These type of PBXs are easier to own and operate, and much cheaper than traditional telephone service with an analog PBX.

To help customers choose what solution best meets their individual needs, TheDigest.com recently discussed the three most important factors to consider when selecting a VoIP-based service.   

Firstly, businesses should know how many calls they expect to place at any one time. Ideally a single port can be used to place one call. So, a SIP trunk with 30 ports allows the business to have 30 inbound or outbound calls at once. However, they may also opt for SIP plans that offer unlimited ports. In this type of scenario, a virtual PBX is more advantageous as it offers unlimited inbound and outbound calling with every extension, so there is no limit on simultaneous calls.

The second important concern to remain mindful of is the availability of IT staff. In the case of hosted PBX, the service provider handles the hardware off-site – including the maintenance and upgrading. With an on-premises IP PBX, a business needs to have someone on staff that can handle the regular maintenance and upgrading of the hardware.

If the business can afford to have employees always around to maintain and maintain the on-premises system, a hosted PBX would be far better option than employing a dedicated IT staff for the job.

Lastly, every organization most closely analyze whether or not they can handle the upfront cost of the PBX hardware. The cost of purchasing, installing and maintaining on-premises IP PBX can be expensive.
