Hosted PBX

A Hosted PBX is a phone system delivered as a hosted service. It’s also known as a Virtual PBX and the advantages companies that use it experience are the elimination of installation, operation and maintenance costs of their VoIP PBX as their VoIP service provider hosts their PBX for them.

The desk sets will plug into your network and all calls are handled at the provider’s location trough the internet. The provider of the hosted PBX charges a monthly fee that is inclusive of a minutes package and all features. Charges can also be at a per minute calling cost.


  • Providers have more resources than users, so new feature sets are possible
  • New feature installation is handled by provider to avoid confusion
  • Picking and canceling virtual numbers is easy and fast
  • Moving a phone system is easy. IP phone is plugged into a broadband connection.
  • Hosted provides edge border controllers or various other kinds of NAT software to help navigate routers
  • Patches and upgrades of the IP-PBX are handled by the provider
  • Loss of Internet or catastrophic event has no effect on operations because calls can be sent to voice mail or a mobile phone.
  • Lower initial equipment cost and set-up cost
  • Easy to add extra lines
  • Upgrades and new features are included


  • Network qualification is performed by the organization or through a partner. Any upgrades are at the customers expense
  • All IP-PBX feature programming is done by the organization or through a partner
  • No maintenance costs of the IP-PBX, but all on-premise and remote phones and network devices are the responsibility of the customer
  • Staff training is the responsibility of the organization or through a partner
  • Monthly service costs may be higher than OnPremise system
  • Extended features, like conferencing, may come with additional costs.
  • Connections and voice quality are a result of Internet connection
  • Loss of Internet results in loss of phone service (settings can be adjusted so that it goes to voice mail or routed to a cellphone)
  • Flexibility of system can be limited by the provider
  • Customization of features may be slow or unavailable depending on provider

OnPremise PBX

On-premise PBX is also known as an IP-PBX phone system. It is similar to a traditional PBX system that resides at a location, such as a computer equipment room or phone closet. Calls can go through a traditional phone company as well as voice over Internet (VoIP) using SIP trunking. The provider can be the one that already provides service, though a SIP trunk can be configured for use with an Internet service telephone provider (ISTP).
