Why Move To Cloud

What you get when you switch from a legacy PBX.

Six structural advantages over old on-premise phone systems — whichever Comstel platform you choose.

Lower monthly cost

Cloud phones typically cut total phone costs by up to 80% versus legacy ISDN, on-premise PBX, or copper-line setups. Predictable per-user pricing — no surprise bills.

One number, any device

Your business number works on your desk phone, mobile app, laptop, or tablet. Take office calls anywhere — home, road, client site, overseas — on the same number.

Scale up or down instantly

Add a new staff member, a new office, or remove a seat in minutes — not weeks. No cabling, no hardware procurement, no engineer visits. Just a quick admin change.

Always up to date

Cloud platforms update automatically with new features, security patches, and improvements. No costly hardware refresh cycles every 5–7 years.

Built-in business continuity

If your office internet drops, calls automatically reroute to mobile apps. If your office is unreachable, you're still in business — on your existing business number.

Modern features standard

Video meetings, team messaging, presence, call recording, voicemail-to-email, auto-attendant, IVR, call analytics — all included rather than expensive add-ons.

Not Sure Which Platform?

Quick guide by team size.

5–1000+ USERS

Mid-Market & Multi-Site

Growing businesses, multi-location retail or hospitality, regional offices. You need more customisation than pre-packaged bundles — integrations, presence, video, CRM links, and the ability to scale.

50+ · CONTACT CENTRE

Enterprise & Regulated

Large corporates, financial services, healthcare, contact centres, or regulated industries. You need enterprise-grade SLAs, dedicated account management, contact centre capability, and the strongest compliance certifications.

Frequently Asked Questions

Common questions about cloud phone systems.

What is a cloud phone system?
A cloud phone system — also called VoIP (Voice over IP) or UCaaS (Unified Communications as a Service) — runs your business phone over the internet rather than traditional copper lines. The phone software lives in secure data centres rather than on hardware in your office, so calls work on any device with an internet connection: desk phone, mobile app, laptop, or tablet.
Which platform should I choose?
Pick by team size and complexity. Up to 50 users with simple needs → BizTel. 5 to 1000+ users needing customisation, integrations, and multi-site → iPECS Cloud. Enterprise, contact centre, or regulated industry → Avaya Cloud Office. Comstel's sales team can recommend during a free consultation.
Can I keep my existing business phone number?
Yes — in nearly all cases. Number porting is included as part of cloud phone migration. We coordinate with your current provider to move your numbers across to the new platform with minimal disruption (usually 5–15 business days). Your old phones keep working until cutover, so there's no period without a phone.
Do I need new handsets?
Depends on the platform. BizTel includes the handset in the bundle. iPECS Cloud and Avaya support a range of compatible IP handsets and softphone apps — or you can run app-only with no physical phones. Comstel will recommend what fits your team's working style.
What happens if my internet goes down?
Cloud phone systems include automatic failover to mobile apps — if your office internet drops, calls keep flowing through staff mobile phones using cellular data. For mission-critical deployments, we also recommend a backup connection like Fixed Wireless NBN or a 4G/5G failover router so the office stays online.
How does cloud compare to my old on-premise PBX?
Cloud is typically significantly cheaper (no hardware refresh, no on-site maintenance), more flexible (work from anywhere, scale instantly), more feature-rich (video, messaging, presence built-in), and more reliable (failover to mobile). On-premise PBX still suits very specific use cases — ask Comstel if you're not sure.
Can I add an AI receptionist to my cloud phones?
Yes. Bonnie AI works with any cloud phone system — or any AU mobile or landline — via call forwarding. She answers calls 24/7, handles bookings, and sends WhatsApp follow-ups. 7-day free trial included; no credit card required.
