The 7 questions IT & finance teams actually ask

IT-grade FAQ

No fluff answers. If it can't be resolved with a number or a clause, it doesn't belong here.

Yes if your system still relies on PSTN, ISDN, analogue fax, alarms or copper-dependent services. We audit those dependencies before recommending Yeastar Cloud, SIP or on-prem P-Series.
Yes. We lodge the carrier port on day 1 of design. Direct-dial, switchboard, fax — all numbers move across with no change to letterheads.
We design failover into the call-flow. Incoming calls can automatically route to 4G/5G softphones, mobiles or an answering path so your business number keeps working.
Cloud PBX suits most SMBs and multi-site teams because it removes server maintenance. On-prem Yeastar P-Series suits industrial sites that need local calling, paging or survivability when internet links drop.
Yes. We map the old call-flow, pre-configure Yealink handsets and softphones, schedule the carrier port and use out-of-hours changeover windows where needed.
Yes. We design queueing and after-hours IVR for clinics, staff/office coordination for schools, and on-prem survivable systems for industrial and Bowen Basin sites.
Year-1 SLA-backed business-hours support is included. Extended packs cover handset swaps, call-flow changes, firmware updates and critical response.
We do not play quote-matching games. What we will do is audit their scope line-by-line and show where Business NBN readiness, failover, call recording, handsets or support differ.
