PBX Platform Frequently Asked Questions

PBX stands for Private Branch eXchange—a business telephone system that connects multiple inbound and outbound lines, managing call routing, voicemail, auto-attendants, and features like find-me/follow-me.
PBX systems originated from switchboard operators who manually routed calls. Over time, PBXs evolved into automated systems that handle call routing digitally and offer advanced features like waiting, voicemail, auto-attendants, and find-me-follow-me.
There are two primary types:
- On-premises (traditional) PBX: installed and maintained onsite.
- Hosted (cloud-based) PBX: run by a provider in the cloud.
  Some organizations also adopt hybrid models that combine both.
A hosted PBX is a virtual, cloud-based phone system managed by a provider via the Internet. It replaces on-site servers with remote infrastructure, routing calls and delivering features over VoIP with lower capital costs and off-site maintenance.
Key advantages include:
- Reduced CAPEX (no hardware).
- Lower maintenance overhead.
- Scalability — easily add/remove lines.
- Faster feature updates—new capabilities included in subscription.
- Reliable disaster recovery—cloud-based failover.
Traditional PBX uses circuit-switched networks, while VoIP systems transmit voice over IP networks. VoIP delivers modern integrations, features, and is more adaptable. Companies often blend analog PBX with VoIP via hybrid models.
VoIP offers app-like capabilities rather than hardware limitations—such as voicemail to email, CRM integrations, softphone support, mobility across devices, and lower maintenance costs—making it a more flexible, application-oriented model.
You must assess your data network’s capacity, quality, and reliability to support high-quality VoIP calls—this is critical before transitioning from traditional analog PBX systems.
Hosted PBX eliminates upfront equipment costs, lowers maintenance, includes calling features as part of monthly pricing, and often reduces taxes or tariffs by leveraging internet calls, enhancing cost-efficiency and flexibility.
Beyond voice calls, modern systems include video, instant messaging, presence, mobility, and integration with collaboration tools—all available on a unified platform to enhance productivity and accessibility.
