Much depends on your business needs and the size of your organization along with the number of extensions required. If you have 15 or less employees or multiple small offices, then choosing hosted business VoIP often remains the preferred choice.

There are Advantages to having and managing your own Phone System

One relevant component that precedes all others when considering a new phone system is the status of your current carrier and if you have a contract. Do you want to switch or add other cost saving options? Many Asterisk based PBX appliances can connect to any type of a telephone provider's service whether it's traditional copper phone lines, a PRI circuit or using SIP/VoIP.

An On premise Asterisk Based phone system:

  • You have control over your network- An Asterisk based premise phone system resides on your network. This eliminates any long distance signaling that occurs with off-premise or cloud based based VoIP systems. Communication from the phone to the PBX server is almost instantaneous, so signaling distance and latency should be non-existent. Failover: If you have traditional phone lines, the PBX can be configured to utilize them if the Internet goes out.
  • Non-proprietary Open Source System- Asterisk based phone systems can use non-proprietary phones and other hardware. This will lower costs and allow for open market choices for vendor neutral hardware. Need a phone, buy it from many online sources.
  • Lower ongoing operational costs- Having your own in-house PBX saves money over time when compared to a hosted model, which probably has lower upfront costs. A business owned phone system will typically result in lower monthly operating costs when spread out over time. This is especially recognized for larger company systems with a higher number of users. The larger the system the more the savings when compared to a cloud based service.
  • Extra cost savings when SIP trunking- Using SIP trunks for low cost calls, both domestic and International, will save money over traditional carriers. When you have your own phone system, you choose which carriers to buy service from. This gives you pricing flexibility.
  • Expandability- Lower cost to add users and extra extensions. Since Asterisk systems are non-proprietary adding more capacity merely requires the hardware, not add-on licensing fees. Users at home can set up remote extensions easily without additional software licensing.
Asterisk based VoIP systems are lower in cost, easy to setup and straightforward to manage.
