Commonly Asked Questions
On-Premise vs. Cloud?
On-premise systems eliminate ongoing per-user monthly SaaS fees and keep your data entirely under your control, whereas cloud systems rely completely on external vendor uptime and constant internet connectivity.
Is a phone line required?
No. Modern local PBX installations utilize SIP Trunking over your existing business internet. This delivers high-definition digital voice channels without requiring ancient copper telephone lines from the phone company.
What if internet drops?
Because the core routing engine sits inside your building, internal desk-to-desk calling, local overhead paging, and intercoms remain 100% operational. External calls can automatically failover to mobile apps or backup lines depending on the carrier you select.

Whether you need to configure a highly customized FreePBX node or deploy a streamlined 3CX system across your company facility, A1 Computers provides the local infrastructure expertise your project demands.
