Your trunk. Your minutes. Our PBX.
sipbox doesn’t sell numbers or profit from your traffic. Bring the SIP trunk from your own carrier and pay per seat only. Minutes stay at your carrier’s direct rate.

One platform — four areas of work
A PBX on your carrier’s trunk
Connect any carrier’s SIP trunk and get a full PBX: voice menus, teams, queues, business hours, recordings. No number rental, no markup on minutes.
- Your own SIP connections and inbound numbers — self-service
- Call flow builder: steps, branches, “if nobody answered”
- Outbound rules by destination — 245 countries
- Greetings recorded or typed — speech synthesis built in
A web phone inside the portal
No desk phone, no software to install: calls run in the browser. SIP registration over a secure connection; microphone and speaker are picked with a sound check.
- Dial pad, hold, call transfer
- Colleagues with live statuses and call pickup
- A second incoming call with line switching
- Do-not-disturb and forwarding from the same window
Supervisor and a live view of the line
See who’s talking, who’s free and how many people are waiting. Listen to any conversation in one click — the platform calls the supervisor’s phone and joins the line.
- Agent statuses and live calls without reloading the page
- Three modes from the handset: listen, whisper, barge in
- Callback requests from the queue with handling history
- Load and missed-call reports
Transcripts and call takeaways

How to launch your cloud PBX in three steps
Bring your own trunk
Numbers and minutes stay with your carrier. Any carrier providing a standard SIP trunk works — authentication by credentials or by IP address.
We connect and configure
Trunk registration, inbound routing, voice menu and teams — from ready templates. We help during onboarding; you don’t need a telecom engineer.
Pay per seat only
A flat price per employee. Zero markup on minutes — we don’t earn from them, so we have no interest in your traffic.
See how much you save
A per-minute PBX compared with sipbox running on your own trunk.
A typical direct-contract rate is 0.4–0.7 ₽/min. Check yours with your carrier.
An estimate, not an offer. The left column uses average public terms of per-minute cloud PBX providers (≈1.5 ₽/min and ≈450 ₽ per seat). Real figures depend on your carrier, destinations and volume.
Solutions for your use case
Ready-made setups per industry and workflow.
Platform features
A full cloud PBX with no carrier lock-in. Below is what works today; anything still in development is marked as such.
Call flow builder
The call path as a ribbon of steps: greeting, menu, team, queue, “if nobody answered”. Each step is written in plain language. Versions and rollback included.
Greetings by voice or text
Upload a recording or simply type the text — speech synthesis produces the greeting. Pick a voice and preview before saving.
Supervisor
Live conversations, agent statuses, queues. Join a call in one click: listen, whisper to the agent or barge in.
History, recordings, storage
Every call with recordings and filters, playback and download, bulk export as one archive. Used space is measured from actual files.
Outbound routing
Rules for “where you may call → through which carrier”, backup connections, a cap on simultaneous calls, emergency numbers. 245 countries in the directory.
Callback from the queue
The caller hears their position and can hang up instead of waiting — the platform calls back. Requests are visible to the supervisor.
Alerts and lists
Missed calls and voicemail by email, call events to webhooks. Blocklists and VIP lists out of the box.
AI summaries and transcripts

Integrations with your stack
Calls and recordings land in the CRM automatically. Bitrix24 works today; other connectors are built on the same integration core as demand appears.
All integrations →How this differs from a carrier-owned PBX
The core difference is the business model. We compare approaches rather than competitors’ price lists — those change, and a claim about them would linger on this page.
This describes the typical carrier-PBX model rather than any specific provider. Check the actual terms with your own vendor.
