Why Move from ISDN to the Cloud?

Provide Business Continuity

Today, a sudden drop-off in phone service can quickly spiral into both lost productivity and lost revenue. Cloud-based solutions offer the continuity, reliability, and security that most businesses simply can't deliver through on-premises solutions—which are inflexible and require much longer deployment times that could lead to a lengthy period of downtime.

Provide Business Continuity
Free Up IT Talent

Free Up IT Talent

A hosted solution means there’s no need to constantly maintain servers on-site—instead, these responsibilities now fall to the cloud service provider. As a result, your IT teams will have more time to devote to delivering projects that align with the wider business’ goals.

Increase Scalability

Cloud-based solutions also offer increased scalability over on-premises alternatives. This means it’s easy to rapidly scale up your communications infrastructure to suit the speed and growth of your business. You can quickly add new employees to their communications systems when required. This ease of use can help your organisation to grow seamlessly—without any costly downtime.

Increase Scalability
Bring Flexibility to Cost

Bring Flexibility to Cost

Pricing is much more flexible with cloud-based communications systems. Instead of paying a fixed rate, you are only charged for the services you actually use. With Fuze, you won’t face a large increase in fees in the event of a sudden spike of activity. You’re also not forced into paying for services you haven’t used during a quiet period. Ultimately, this saves you money up front since every employee’s phone usage might differ.
