- One-off setup & porting (design, testing, training)
- Ongoing support (monitoring, updates, MACs)
Internet readiness
- Stable link with low jitter; prioritise voice using QoS and a voice VLAN.
- If you’re remote, Starlink can work well; pair with 4G/5G failover for 000 resilience. See our internet guide above.
Migration roadmap (no downtime drama)
- Discovery – list numbers, lines, call flows, ring groups, queues, voicemail boxes.
- Design – draft your IVR, hours, holidays, escalation paths; map extensions.
- Build – configure 3CX, SIP trunk, caller ID, queues, digital receptionist, voicemail-to-email.
- Test – inbound/outbound, transfer, voicemail, call recording, mobiles, presence.
- Port – schedule porting window outside peak hours; forward calls during cutover.
- Train – 20-minute team sessions + a one-pager “How to answer/transfer/park”.
- Go-live – monitor closely in week one; tweak queues and greetings.

FAQs
How long does porting take? Simple ports can be quick; complex services take longer—plan for a safe window.
Do we need desk phones? Not necessarily. Many teams go 100% softphone with quality headsets.
What if the internet drops? Use mobile apps, dual-WAN and call-forward failover.
