Hybrid / On Premise PBX

Onsite services, often also referred to as On-premises solutions, are PBX / VoIP solutions managed by hardware or a server located on-site and maintained and managed by the business’s IT department

What is Hybrid PBX?

The onsite PBX is also known as an on-premise IP-PBX phone system. It is similar to a traditional PBX system in that it resides at a single location, such as in a computer equipment room or phone closet.

The signalling is done with an IP phone to the IP-PBX server using a LAN. Calls can go through a traditional phone company or as VoIP using SIP trunking. Gateway cards can be used to connect the system to traditional lines.

Hybrid PBX benefits:

Feature rich – Features available are typically greater in both quantity and complexity.

SIP – The integration of a SIP trunk offers free call packages and calls using IP. This provides cheaper call costs than routing calls over analogue lines.

Ownership – Having something tangible that you can call your own.

No single point of failure – Typically multiple analogue and SIP lines are used to route calls, this presents multiple options if a single line was to go down or develop a fault.

Unified Communications – Onsite phone systems today facilitate so much more than just phone calls. They include capabilities of instant messaging, video conferencing, voice conferencing and visual voicemail.
