PhoneDesk
PhoneDesk Box

A phone system is not a download.
It arrives as a device.

PhoneDesk is ten services on two machines, a carrier trunk, certificates for the browser and a dialplan that fits your organisation. We deliver that as a fully commissioned system - hosted in Germany or as a device in your server room. And we keep running it.

Why a device

Software can be downloaded. A phone system has to keep running while nobody is watching.

A phone system is real-time infrastructure. It holds connections open, it sits on the internet with a SIP port, it registers with a carrier, and it has to work at eight on Monday morning. That is why we do not ship PhoneDesk as a module for you to install yourself, but as a commissioned system with a service contract.

What's inside the box

System, control layer, voice AI - wired up and ready

You do not get a build-it-yourself project. You get a system that answers your numbers, records every call in Odoo and whose dialplan you change from inside Odoo.

The system itself

Asterisk 22 LTS, up to 50 concurrent calls, a dedicated SIP endpoint per seat. Set up, hardened and connected to your carrier.

preconfigured

The dialplan as an Odoo record

Which number rings where is no longer an SSH session: generate, dry-run check, roll out, read back from the running system. If the system deviates, the change rolls back automatically.

with rollback

Calling in the browser

Answer, dial, attended transfer, conference - in the Odoo window, without a desk phone. Click-to-dial from any Odoo record. We set up the certificates this needs and renew them.

no desk phone

Voice AI on the device

On the Box M, speech recognition and speech synthesis run locally on the device. The AI answers, holds the conversation and writes a summary and the transcript onto the contact in Odoo - with sentiment and topics.

local on the box

Consent, retention, audit trail

Over the recordings your system already produces sits the layer an auditor wants to see: a consent register with grant, refusal and withdrawal, retention periods per tenant, deletion by key destruction, and an audit trail from which nothing disappears, not even under administrator rights.

audit-proof

Secured from the start

Blocklists against registration attempts, firewall, restricted SIP sources. Changes to the system go through Odoo, not through an SSH session - including key rotation without a console.

hardened
Bottom line: a phone system you do not have to run yourself - delivered, commissioned, monitored and maintained remotely.

In detail

What each model delivers

The same software on all three models. The difference is where the machine sits, the voice AI and the response time.

Odoo Community is enough. PhoneDesk does not need an Enterprise licence.

Managed Service

What we actually do to a phone system

A phone system is not a server handing out files. It sits on the internet with an open SIP port, it hangs off a carrier, and a mistake shows up on the phone bill at the end of the month.

SIP security and fail2ban

Blocklists against automated registration attempts, plus a monthly review of the permitted sources. An unwatched SIP port is the most common route to toll fraud.

Certificates for WSS

Without a valid certificate no browser registers with the system. We renew the certificates and keep an eye on the remaining validity - before they expire.

Monitoring the carrier trunk

We check continuously that your system is registered with the provider. A silent loss of registration is the outage nobody notices - until the first customer cannot get through.

Change windows for the dialplan

Two changes a month are included: generate, dry-run check, roll out, read back from the system. If the result does not match, the change rolls itself back - with a history.

Asterisk security updates

We apply security releases within 72 hours. Before that we check whether the templates on the box still match the release. This is exactly where unattended updates go wrong.

Replacement unit and monthly report

If hardware fails, a prepared replacement unit is sent. Once a month, a report in plain language: health, calls, updates applied, open points.

On the roadmap

What is not in the scope of delivery today

These four points are not in the lists above because they do not ship today. We name them before the quote, not after.

from Q4 2026
Call recording
Today PhoneDesk governs consent, retention, access and deletion for recordings your system produces. PhoneDesk does not start the recording itself.
from Q4 2026
Call quality reports
Availability is something we commit to today. Voice quality figures such as MOS and jitter come with the next stage of the monitoring.
from Q4 2026
Spend guard for outbound calls
A spend cap with an alert for outbound calling. Until then, restricting the SIP sources remains the safeguard against toll fraud.
from Q4 2026
Box L - language model on site
Speech recognition and speech synthesis run on the Box M today. The language model is added with the Box L, together with the MindDesk Appliance.

Not planned: call queues, hunt groups, voicemail, call park, supervisor listen-in and a mobile app. If you need those, we are the wrong fit - and you will hear it in the first conversation.

Your phone system, without you running it

We match model and size to your organisation, commission the system at a fixed price and keep it running. You keep your numbers, your carrier and your data.

Purchase or leasing

The box does not have to become a fixed asset

Some organisations buy the hardware, others want no investment on the balance sheet. Both work. With leasing we are expressly not the lessor - the financing runs through a leasing partner.

Purchase

Hardware once, then only the ongoing operation. The system is yours, and so is the licence - permanently, per Odoo database.

2.900 € / 5.900 € one-time

Leasing through a partner

36-month term, even small amounts can be financed. The hardware sits on the lessor's balance sheet, you pay a fixed monthly instalment alongside the Managed Service.

Box S around 90 €/month

Hosted, with no hardware at all

Box V: no purchase, no depreciation, no device in the server room. The machine sits in a German data centre and is run by us.

349 €/month

You have your own hardware

Then we deliver commissioning and operation only. The service contract follows your licence tier - from a small setup to a multi-tenant structure with evidence obligations.

299 € / 499 € / 799 € per month

Example leasing calculation: around 90 € a month for the Box S over 36 months. The binding terms come from the leasing partner.

Three years, calculated

Against a per-seat cloud PBX

An organisation with 25 staff and 18 phone seats, today on a cloud PBX. Both sides over 36 months, with the same costs for trunk, numbers and call minutes.

The honest reading

Over three years PhoneDesk costs roughly twice as much

About 31 € more per phone seat and month. We write that down because otherwise you would work it out yourself. You do not buy PhoneDesk to cut telephony costs. You buy it to stop typing up phone calls, to make number routing auditable and to have what was said in your own Odoo.

Delivery and go-live

How a box reaches you

Not a project running for months. But not a cardboard box you cable up yourself either. We reckon on around 20 hours of work on our side, spread over seven steps. We currently ship fewer than one box a week - which is why we agree dates in advance instead of promising them and missing them.

  • 1 Clarify size and carrier - seats, numbers, provider, existing system.
  • 2 Prepare the device - operating system, services, credentials, all on our premises.
  • 3 Network and certificates - connection, firewall, SIP sources, certificates for the browser.
  • 4 Carrier trunk - registration with the provider, map the numbers, test calls in both directions.
  • 5 Connect Odoo - dialplan as Odoo records, one endpoint per seat, click-to-dial.
  • 6 Switch on - attended transfer, conference, voice AI with a German voice and your greeting.
  • 7 Acceptance and handover - test calls in the browser, briefing, operation begins.

Frequently asked questions

What customers ask about the box

Why can I not simply download PhoneDesk?+
Because a phone system is not an Odoo module. Running it takes ten services on two machines, eighteen sets of credentials, a carrier trunk, certificates for calling in the browser and a dialplan that fits your organisation. Eleven of those steps nobody does automatically. That is why we deliver a commissioned system and keep running it - and why commissioning is a line of its own in the quote.
Does the device have to sit on my premises?+
No. The Box V is a machine in a German data centre that we run - with no purchase and no device in the server room. The Box S and the Box M are the route for organisations that need the system on their own network. The software is the same on all three models.
Does the voice AI really run on the device?+
On the Box M, speech recognition and speech synthesis run locally on the device - the audio is processed there. The language model itself is connected in; bringing it onto the box is planned with the Box L for Q4 2026, together with the MindDesk Appliance. Before the quote we write down for you which part computes where.
Does PhoneDesk record calls?+
No. PhoneDesk does not start a recording. What PhoneDesk does: over the recordings your system already produces, it lays the layer an auditor wants to see - consent with grant, refusal and withdrawal, access blocked where there is no consent decision, retention periods per tenant, deletion by key destruction, and an audit trail from which nothing is removed, not even under administrator rights. A recording function of its own is on the roadmap from Q4 2026.
What happens if something fails - and what about at night?+
If hardware fails, a prepared replacement unit arrives the next working day; for the hosted Box V we rebuild the machine within four hours. We commit to a response by a human Mon–Fri from 08:00 to 18:00, within four to eight business hours depending on the model. Outside business hours we commit to no response - that is how it reads in the contract.
What does getting started cost, and when does it pay off?+
Hosted: 2.400 € commissioning at a fixed price and 349 €/month. As a device on site: 2.900 € hardware, 2.900 € commissioning, 449 €/month - with voice AI 5.900 €, 3.900 € and 649 €/month. On top comes the PhoneDesk licence per Odoo database. In our example calculation with 18 phone seats, the extra spend against a cloud PBX is earned back after 10,9 months. Below about ten phone seats no variant pays off.
