? About the role

Aged Care Decisions runs contact centre teams across Australia and offshore, all on 3CX. We’re looking for a hands-on 3CX and telephony specialist to own our voice and SMS environment: keep it running smoothly, look after day-to-day changes and support, and make sure it’s well documented.

This is a remote, part-time contract of around three months:

- Month 1: one day a week. Handover, getting to know our setup, and picking up open support items.

- After that: around four to eight hours a week for routine support, with extra hours agreed as needed.

- Major outages: we’d like to agree a coverage window and response time with you for critical failures (e.g. queues down, inbound calls failing). Tell us what you can offer.

?️ What you’ll do

- Administer and troubleshoot 3CX v20: users, extensions, queues, ring groups, IVRs, business hours, voicemail and inbound/outbound call routing

- Manage SIP trunks, phone numbers, caller ID, number allocation, porting and routing changes; maintain an accurate number and service inventory

- Support inbound, outbound and two-way SMS; trace delivery failures across carriers, messaging providers and our business systems

- Diagnose call quality, dropped calls, one-way audio, registration and connectivity issues using call records, logs, packet captures and network diagnostics

- Own supplier escalations through to verified resolution

- Maintain our Linux-based 3CX environment on AWS: monitoring, backups, security and controlled updates

- Own the 3CX and carrier side of our integrations (call recording, Microsoft Teams presence, CRM): configure and test APIs and webhooks, troubleshoot issues and write small telephony scripts where needed.



Our developers own application code changes; you’ll help define what’s needed and test the full flow with them

- Review carrier invoices, call classifications and usage charges; investigate discrepancies with suppliers and finance

- Document routing, configuration and support procedures, with tested changes and rollback plans

✅ What you’ll bring

- Proven hands-on 3CX administration and troubleshooting, including v20 and contact centre queue and routing configurations

- Strong SIP/VoIP and networking skills: DNS, firewalls, NAT and audio troubleshooting; comfortable reading logs and packet captures

- Experience with Australian carriers, number porting, and SMS delivery and routing across multiple suppliers

- Practical Linux and AWS skills; hands-on with REST APIs, webhooks and light scripting for communications integrations

- Transparent communication, reliable follow-through and concise documentation; able to work independently and remotely
