VoIP Phone System

VoIP phone system: IP PBX, direct inward dialing and SIP trunking, done properly.

A full VoIP phone system, not just a softphone app. IP PBX call routing, direct inward dialing numbers, and SIP trunking, managed end to end.

What is a VoIP phone system?

A VoIP phone system routes calls over your internet connection instead of traditional copper telephone lines. At the centre of it sits an IP PBX, the software that handles call routing, voicemail, hunt groups and IVR menus. The result is a phone system that's cheaper to run, easier to scale, and works from anywhere your staff have an internet connection.

  • Works on desk phones, mobile apps, or softphones

Direct Inward Dialing

Direct inward dialing: every extension, its own number.

Direct inward dialing (DID) lets external callers reach a specific extension directly, without going through a receptionist or an auto-attendant first. Instead of a company needing a physical line per phone, DID numbers are assigned in software, so scaling from 5 extensions to 50 is a configuration change, not a wiring project.

Direct department numbers

Sales, support and accounts each get their own number, routed straight to the right team.

Faster call resolution

Returning customers reach the same person directly, no re-explaining through a switchboard.

Scales with your team

New DID numbers assigned in minutes as your team grows, no physical line installation.

Keep your existing numbers

SIP trunking lets you port existing landline numbers onto your new VoIP phone system, so customers keep dialling the number they already know.

SIP Trunking

An IP PBX solution that fits how you already operate.

SIP trunking is the technology that connects your IP PBX to the public phone network, letting you make and receive calls to any number, mobile or landline, without maintaining physical telephone lines. It's what turns a VoIP PBX from an internal intercom into a full replacement for your existing phone system.

  • Number porting handled for you, minimal downtime
  • Concurrent call channels sized to your call volume
  • Redundant routing if one carrier path has issues
