Modern voice can look complicated because business requirements, phone hardware, cloud services and networking all meet in one place. This page gives you a sensible route through it.
If you are new to VoIP
- Read What is VoIP? to understand the core idea and terminology.

If you are choosing a system
Begin with outcomes: how calls should reach people, how many locations and remote workers you support, what happens during an outage, which applications must integrate, and which numbers must be retained. Only then compare products.
If you support phone systems
Our technical paths will cover SIP signalling, RTP media, provisioning, firewalls, NAT, VLANs, QoS, packet analysis and vendor-specific administration. Device libraries for Yealink, Fanvil and Grandstream are being developed first, followed by Poly, Jabra and other platforms.
A note for Australian readers
Global concepts apply in Australia, but phone-number formats, emergency calling, regulation, number portability, carrier interconnection and access-network conditions can differ. We call out Australian details wherever they affect a decision or procedure.
