Phone system deployment can be an important long-term decision that would either give you a peace of mind or torment you over issues on scalability and technical support issues. PBX (private branch exchange) setups may be a popular option given its commonplace in today’s market. With advances and commoditization of cloud services, it is increasingly popular to adopt cloud-based solution including office telephone systems.
There is hardly any doubt that a cloud deployment could be completed faster than onsite deployment.
An on-premise PBX deployment involves installation and configuration of the hardware.
Cloud telephony system simply involves configuring the flow of calls over the web browser followed by terminating SIP extensions on the deskphones or mobile devices to get started.
To the customers, it could be as simple as communicating your requirements and receiving pre-configured phones that is immediately ready for use upon connection to internet.
Cost and Scalability
You have just bought the phone system and installed by your provider. Now it’s doing what it was designed to do. Suddenly, its not. With an on-premises PBX approach to business communications, businesses may seem to have saved on a one-time purchase but more often, a varying combination of demands may require reconfiguration, hardware upgrade and other sources of cost.
Your IT team can be caught off guard with unforeseen cost spikes during upgrades, replacement or expansion are required. These costs increases as companies become bigger. With replacement cycles are getting shorter and capabilities advancing at an ever-increasing rate, your team may find such cost to be increasingly significant.
Furthermore, On-premises PBX servers can simply stop working with when caught with surprise compatibility problems that force an unplanned upgrade.
PBX system are less scalable—they’ve got to be done in big investment blocks and significant effort all at once.
Cloud hosted PBX operates on a Software-as-a-Service model and charges on a per-user basis per month, quarter or year. While the company may not get the budget breaks they do with an on-premises system, they also avoid potential large, unpredictable spikes in costs.
The business grows? Cloud-based system can simply grow with it—and not in awkward transition resulting in either in periods of strains and periods of underused capacity.
Having an on-premise PBX exposes the system to an additional point of failure which can demand a longer support lead time. This can be failure from unplanned upgrade, poor maintenance of equipment and accidental disconnections from power or internet, resulting in unwanted downtime.
Whereas on cloud systems, any potential problem you may face may have been flagged by other users and resolved before you even realize it.
Going with a on-premise PBX system may appear to be a cost-saving options. However, retainer fee for your system integrator for system maintenance would also increase based on the number of extensions and complexity of the deployment. Going cloud not only reduce immediate cash investment, but also turn out to be cost saving in the long term factoring in maintenance and upgrades.
