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.
