 Hosting The entire business phone system is hosted by your VoIP service provider The system is hosted by the business in the same location where service will be used The phone system can be hosted on an on-site server, or remotely in a datacenter
Deployment & Maintenance The VoIP provider will host the service, which is why it’s also called “Cloud PBX” or “Virtual PBX” You will require  internal or external IT support to install and maintain your IP PBX
Scalability A Hosted PBX system can be upgraded or downgraded at any time The on-site IP PBX will be limited to the number of users it can support, so you will need to ensure that size changes are taken into consideration Software IP PBX systems, just like the Hosted PBX ones, can be configured for more or less users, depending on the business’ needs
Flexibility Being hosted in the cloud, this office phone system can be accessed independently of location The users of this PBX have to be located in the same network, thus if you have multiple locations, each will require its PBX Users can connect to a software IP PBX from any location, making it ideal for multi-office or on-the-road setups
Stability and availability All business phone systems are as stable and reliable as the server that they are hosted on. The Cloud PBX is stored by your provider, so they will be in charge of providing a redundant connection and an adequate bandwidth, while with your own IP PBX you are responsible for ensuring the stability of your servers and network.
Price A good Virtual PBX system will start at around $15.99/month/user IP PBX hardware can start at $250 and go up to a few thousands, depending on size. SIP Trunking services start at around $7.99/trunk/month PBX software licenses start at $300/license, depending on calls allowed, in addition to SIP Trunking from $7.99/month/trunk. There are also providers who offer it as SaaS (software as a service)
Features The number of features and their level of complexity depends a lot on the quality and the price of your PBX, whether it’s a hosted phone system, and on-site hardware-based one, or a software
Security The security is all in the hands of your business phone service provider You will be responsible for deploying security solutions on your PBX dialplan, servers and network


A Hosted PBX is the solution for you if you are looking for a hassle-free business phone system. Your VoIP provider will handle all the elements of hosting, configuration and maintenance, while no upfront investment is needed. Having your own IP PBX means lower monthly fees, the possibility to have full control over your configuration, but also requires that you have knowledgeable IT staff who can install, configure and maintain your PBX.  Whatever your choice is, ensure that you have analyzed all options and you and your team are ready for the challenge that is a VoIP office phone system.  This thorough preparation will enable you to fully enjoy the opportunities your new phone system will bring your business.
