Digital PBX Questions
Everything about PBX design, installation, and features.
What is a PBX and why does my business need one?+
A PBX (Private Branch Exchange) is the system that manages all telephone calls within your organisation — routing internal calls between extensions without using external lines, and connecting to outside telephone networks for external calls. Without a PBX, every phone in your office would need its own telephone line. A PBX lets dozens or hundreds of users share a small number of external lines, adds features like IVR and hunt groups, and dramatically reduces your monthly telephone bill.
What is the difference between a digital PBX and an IP PBX?+
A digital PBX uses proprietary digital signalling over dedicated telephone cabling to connect phones — reliable and proven, but less flexible. An IP PBX uses standard Ethernet cabling and SIP protocol — phones connect through your data network, softphones work on laptops and mobile phones, and configuration is done through a web browser. Layerix deploys both, and can bridge existing digital systems with new IP infrastructure during phased upgrades.
How many extensions can a PBX support?+
Entry-level systems support 8–32 extensions. Mid-range platforms support 50–300. Enterprise systems scale to thousands of extensions across multiple sites. We size the platform for your current headcount plus planned growth — and document the capacity in the design before any hardware is ordered.
Can the PBX support staff working from home or remotely?+
Yes. IP PBX systems support remote extensions through VPN or direct SIP registration over the internet. Remote staff can use a desk phone, a softphone on their laptop, or a mobile app — and they appear as a normal extension to anyone calling them internally.
What is an IVR and how do we set it up?+
An IVR (Interactive Voice Response) is the auto-attendant that greets callers and routes them — 'Press 1 for Sales, Press 2 for Support.' Layerix records or imports your greeting audio, builds the call flow in the PBX, and tests every path before handover. Changes to IVR menus after handover are made through the admin web interface, which we train you to use.
Can you integrate call recording for compliance?+
Yes. Call recording can be configured per extension, per group, or all-calls. Recordings are stored locally on the PBX or on a separate server. For financial services or call centres with compliance requirements, we configure recording to meet your specific retention and access control policies.
What happens to calls if the PBX goes offline?+
We configure failover routes for every deployment where uptime is critical — typically routing calls to mobile numbers or a secondary site if the primary PBX is unreachable. SIP trunk providers also support failover routing at their end. We test failover before handover on every project.
Can we keep our existing phone numbers?+
Yes — number porting moves your existing numbers to your new SIP trunk provider. We assist with the technical configuration required on the PBX to receive ported numbers. The porting process is between you and your telecom provider, but we coordinate the technical requirements on your behalf.
How long does a PBX installation take?+
A small office system (up to 30 extensions) typically takes 1–2 days. A 100-extension deployment takes 3–5 days. Large or multi-site projects are scoped individually. We provide a project timeline before work begins.
Do you supply the PBX hardware or only install?+
Both. Layerix can supply and install, or install hardware you have procured. We are experienced with Panasonic, Grandstream, Yealink, Cisco, and Avaya — and we recommend the right platform for your scale and budget.
What ongoing support do you offer after installation?+
We offer AMC contracts covering firmware updates, configuration changes, fault response, and annual system health checks. We also offer Break Fix response for one-off incidents, and Resident Manager or Service Manager engagements for larger enterprises that need ongoing dedicated support.
