A
premises-based PBX solution (also known as an IP PBX) is dependent on a voice server kept on-site in the equipment/server closet. Physical phones are located throughout the office. Calls can route through a traditional phone company as well as over the internet using SIP trunking.
Hosted PBX is a cloud voice solution where the provider manages/maintains the voice server in a cloud data center. The only equipment in the office is physical phones. Calls route over the internet using SIP trunking.
On-Premise PBX
Cost – higher upfront costs and set-up fees. Above a certain threshold, it might be cheaper to own equipment than pay a monthly fee, but servicing and maintenance can get expensive. When using only basic call features with >25 phones per store, the total cost of ownership is less over a 5-year period
Scalability – purchase phones to expand (in addition to any
licensing required). PBX needs to be able to accommodate growth and the possibility
of complexity with added features
Failover – if the issue with PBX in-store, calling is affected
and potentially down until PBX can be repaired via a service contract
Maintenance – managed services contract (with phone vendor)
required for software patching and maintenance to ensure security and uptime
Hosted PBX
Cost – usually low upfront costs, the monthly fee per user.
Typically, the low total cost of ownership as a hosted provider takes care of the server
configuration, maintenance, and software patching
Scalability – purchased or leased IP phones added to service
plan, picking and canceling numbers and moving phone system is easy and quick
Failover – calls can be rerouted to cell phones if an issue with
SIP trunk quality, power at a store or catastrophic event. Safeguards at off-site facility include back up power sources, geographic redundancy of data centers,
active-active failover of servers, etc.

The most immediate perk of DaaS is mobility. Employees can access files and software no matter where they are and regardless of if they’re using a laptop, tablet, or another desktop. There’s no more waiting to access or work on collaborative files, ensuring faster turnaround and meeting due dates.
There are four different types of cloud computing: private, public, hybrid, and community. A public cloud is where the whole computing infrastructure is housed at an outside location. A private cloud is when you host your own infrastructure and do not share; this is the highest control level in regards to security. With a hybrid cloud, you combine both public and private services, allowing you to defer some costs but still maintain high levels of privacy. Finally, a community cloud is shared between organizations that share a specific goal, whether it’s a business or an organization.
