Hosted cloud PBX
Your phone system,
without the phone system.
Numbers, extensions, auto-attendant, queues, voicemail and recording — running on telephony infrastructure we wrote and operate ourselves. No PBX in a cupboard, no reseller layer between you and the people who can fix it.

Aria softphone, included on every plan
Pick your numbers
Search and buy DIDs directly in the dashboard, or bring numbers you already own.

Plug in phones
Auto-provision desk phones from six vendors, or hand your team the softphone.
Routing
Calls land where they should
A dial plan engine with pattern matching and prefix manipulation, ring groups that ring all or round-robin with failover, and time-based rules that know your hours and your timezone.
- Auto-attendant with multi-level IVR menus
- Ring groups and hunt groups
- Call queues with longest-idle routing
- Blind and attended transfer
- Call park with timeout fallback
- Forwarding on busy, no-answer or always
Media
The audio path is ours
Calls run through our own Rust media relay rather than a third-party platform. That means NAT traversal, encryption and recording behave predictably, and when something needs fixing we can fix it.
- NAT-aware RTP relay with SRTP
- Music on hold, per-tenant classes
- Call recording with per-extension policy
- Conference rooms, PIN protected
- Built-in STUN for NATted endpoints
- Stereo recordings — each party on a channel
Operations
Built to be run, not just launched
Multi-tenant from the ground up, with the unglamorous parts done properly: billing that reconciles, emergency calling that complies, and a SIP firewall that assumes the internet is hostile.
- CDR rating with per-minute plans
- E911 with validated addresses
- SIP firewall: rate limits, ban lists
- Clustered nodes with shared state
- WebSocket events for call state
- Presence and busy-lamp-field
Hardware
Keep the phones on your desks.
Auto-provisioning configs are generated for six handset vendors, so a phone comes up registered without anyone typing a SIP password into a web UI. Standards-compliant SIP throughout — if your handset speaks SIP, it will work.
