How it works

What this service covers in practice.

Microsoft Teams Direct Routing is the dominant path for Sydney businesses already running Teams for meetings and messaging. Extending Teams to handle calls means users answer on the same interface they use for every other communication — no separate softphone app, no second directory, no calls going out on the wrong number. We licence Teams Phone through CSP, configure Direct Routing via a certified SBC, and port your existing DIDs to our SIP trunks. Most businesses complete the transition over a single weekend with no call interruption.

Legacy PBX removal is the other side of the migration. An ageing on-prem PBX is a maintenance liability, a skills dependency, and a single point of failure that most businesses cannot see until it fails at the worst possible time. We document the existing dial plan, auto-attendant logic and ring groups, replicate them in the new platform, and run parallel operation for two to four weeks before decommissioning the old hardware. Yealink, Polycom and Cisco SPA handsets re-provision onto SIP in place where the hardware is reusable; we replace only kit that cannot support TLS and SRTP.

Call analytics separates a modern phone system from a line rental with features bolted on. Wallboards surface queue depth and wait times in real time so a team leader can shift allocation during a spike. Historical reporting answers the question every business eventually asks: how many calls did we miss, and when? Missed-call rate by hour, abandonment rate by queue, agent handle time — this data shapes staffing decisions and scheduling. We configure the analytics layer at onboarding so the business has baseline data from day one, not six months later when the need becomes urgent.

Compliance recording is increasingly a requirement for Australian regulated businesses. Financial services, healthcare, and legal firms operate under ASIC, APRA, and Privacy Act obligations that require call recording, retention scheduling, and access-controlled retrieval. Our hosted PBX platform records all calls by default, stores them in encrypted storage for the configured retention period, and provides compliant retrieval to authorised users only. We scope recording and retention policies against your specific regulatory obligations so the policy matches the rule — not a generic template that misses the edge cases regulators look for.

Quick answers

Things people ask before signing.

The most common questions on this service. If yours isn't here, send it through — we reply within one business day.

How long does number porting take?
Most porting completes inside seven business days. We submit the LNP request, coordinate with the losing carrier, and run a parallel-route test on the day of cutover so no calls drop. Toll-free and large blocks may take longer; we quote a date in writing.
Can we keep our existing handsets?
Most modern SIP handsets (Yealink, Polycom, Cisco SPA) are reusable, we re-provision them onto our PBX in place. We will tell you up-front if your kit is too old to cleanly support TLS + SRTP, since unencrypted SIP is no longer a supportable baseline.
Do calls work from home and on mobile?
Yes. The soft client runs on iOS, Android, macOS, and Windows. Same extension, same caller-ID, same voicemail across every device. There is no separate "remote-work add-on" fee, every seat is full-feature wherever the user is.
What happens if the internet drops at a site?
Two layers: inbound calls auto-route to a configured fallback number (mobile, another site, or auto-attendant), and softphones running on mobile data continue to take calls. Most users do not notice an ISP outage on the voice path.
How is billing handled, per minute, per seat, or both?
Per seat per month, with national and mobile minutes pooled across the account at carrier rates. Inbound is included. International is a published per-minute rate, not a hidden surcharge. Itemised CSV invoices arrive on the first business day each month.
Move your phones off the PSTN, properly.

Tell us how many seats, your existing handsets, and your number list. We'll come back inside one business day with a fixed-price quote, a port-out plan, and the cutover date we can hold. The conversation is with the engineer who'll run the cutover, not a phone-number salesperson.
