IT Solutions › Cloud phone system
The company phone system,
without the PBX.
Extensions anywhere, all your company numbers ringing on desk phones, computers and smartphones, no hardware to maintain. The AtWorkStudio cloud PBX runs on Asterisk, on an instance dedicated to your company, in a European cloud, an Italian cloud or on your premises, managed by us. If you prefer 3CX or live inside Microsoft 365 with Teams Phone, we design and manage those.
The on-premises PBX has had its day.
A box in the server room, cards to replace, a technician to call for every new extension, and people working from home forwarding the number to their personal mobile. Telephony today is a data stream like any other: SIP lines, extensions anywhere, rules that change in minutes. The PBX becomes a service, and we run the service.
SIP, WebRTC, Opus
The SIP standard that all modern telephony speaks, in its current form: PJSIP stack, calls from the browser too with WebRTC, HD audio with the Opus codec, TLS and SRTP encryption. Plus REST APIs to connect the PBX to CRM, business software and AI-based voice agents.
Every extension
Every extension rings on the desk phone, softphone and smartphone, in the office or working remotely, with the same answering rules, the same hours and the same voicemail. And as many numbers as you need: sites, departments, direct lines and new numbers, on the same PBX.
Zero maintenance
The phone system becomes a service: an instance managed by us, in the cloud or on your premises, IP phones supplied or included in the fee if you want them, updates, backups and security on us. No appliance to buy, power and replace every five years.
What the service includes
One platform, three routes, a single operator.
We design, activate and manage the phone system. You decide how to answer the phone, we make sure it works.
AtWorkStudio PBX on Asterisk
Our reference platform: Asterisk, open source, on an instance dedicated to your company and managed by us. SIP extensions, auto-attendant (IVR), queues and ring groups, business hours and holidays, voicemail delivered by email, music on hold, call recording where needed and in compliance with the law.
3CX or Microsoft Teams Phone
If you already have 3CX or prefer it, we install and manage it, with licences you buy directly from 3CX or one of its partners. If you want full integration with Microsoft 365, the route is Teams Phone, with calls to the public network through an operator or Microsoft calling plans. Same analysis, same design, same management.
Numbers and trunks: they stay yours
We recommend that you subscribe to SIP trunks directly with a provider of your choice: lines and numbers stay in your name and you are not tied to us. Through our professional services we support you in number porting and in dealing with the provider, from the request to the day of the switch.
Desk phones, softphones and smartphones
SIP-compatible IP phones: we supply them, include them in the service fee or you use your own, if compatible. On computers and smartphones, any SIP-compatible softphone of your choice. The same extension rings everywhere and, if you want, you call from your smartphone with the company number, not your own.
Voice security
Encrypted signalling and audio (TLS and SRTP) and the most advanced security protocols as standard, not as an option. Against toll fraud: restrictive outbound rules, blocking of high-risk destinations, automatic blocking of failed access attempts, traffic limits and monitoring. The instance sits behind a firewall we manage, in the cloud and on your premises.
Ongoing operations
Platform updates, configuration backups, monitoring. Changes to extensions, IVR and schedules, call reports, custom configurations and new requests go through our professional services. From the same team that can also manage your network, firewall and Microsoft 365: a single point of contact, even when the problem is not the phone system.
How it works
From today’s lines to a cloud phone system.
Four steps, with the old PBX switched on until the moment of the change. Telephony does not stop: it moves.
Platform, hosting and rules
Design
We choose the platform together (Asterisk, 3CX or Teams Phone) and where it runs (European cloud, Italian cloud or your premises), design IVR, queues, ring groups and schedules, and define the devices.
Porting and phones
Activation
We configure the instance, provision phones and softphones and support you through number porting with your trunk provider. The old PBX stays on until the switch.
Every day
Operations
Updates, configuration backups, monitoring. Changes, reports and custom configurations through our professional services.
Managed service
A service,
not a box.
We do not sell a PBX: we design it, activate it and keep it running. The reference platform is Asterisk, on an instance dedicated to your company, because it gives us full control and has no per-extension licences. Trunks and numbers stay in your name, and the exit terms, including the return of the configuration, are defined in the contract as our ISO/IEC 27001, 27017 and 27018 certifications require.
Where it runs is your choice: a European cloud under US or EU sovereignty, an Italian cloud under Italian sovereignty, or your own premises. For full integration with Microsoft 365 the route is Teams Phone or 3CX. The service is subscription-based.
Asterisk
Open-source engine in development since 1999, behind many commercial PBX products. No per-extension licence, a dedicated instance per customer, hardening and updates handled by us.
4 options
European cloud under US sovereignty, European cloud under EU sovereignty, Italian cloud under Italian sovereignty or on-premises at your site: the choice depends on your compliance requirements, not ours.
Professional services
Changes to extensions and IVR, reports, custom configurations and support in number porting go through our team: a single point of contact, the same one that can manage your network, firewall and Microsoft 365.

Frequently asked questions about the cloud phone system
The questions we hear before moving telephony to the cloud.
A cloud phone system does everything a traditional PBX does (extensions, transfers, auto-attendant, queues, voicemail) but the software does not run on a box you have to maintain in your office: it runs on an instance dedicated to your company, in the cloud or, if you prefer, on your premises, managed by us. Phone lines arrive as SIP trunks, i.e. as data streams over the Internet, and extensions are IP phones, softphones on the computer or an app on the smartphone. The result: the company’s numbers, as many as needed, ring wherever the person is, with no hardware to power, update and replace, and with changes made remotely in minutes.
Asterisk is the open-source telephony engine behind many commercial PBX products and has been in continuous development since 1999. We use it as our reference platform because it gives us full control of the configuration and has no per-extension licence fees. Trunks and numbers stay in your name and the exit terms are written into the contract, as our ISO/IEC 27001, 27017 and 27018 certifications require: you are not tied to us. Asterisk’s robustness depends on how it is installed, protected and maintained, which is exactly our job: updates, hardening, configuration backups and monitoring are part of the service, not an extra.
Yes, and they stay in your name. We recommend that you subscribe to SIP trunks directly with a provider of your choice, so that lines and numbers are yours and you are not tied to us. Number portability is guaranteed by Italian regulation: you handle the request with your provider and we support you through our professional services, from the request to the day of the switch. Timing depends on the losing operator, usually a few working days. We plan the switch so that the old PBX stays live until the moment of the change and the window of unavailability is as short as possible.
A connection sized for the number of concurrent calls, which we verify before activation, a local network with voice traffic prioritised (QoS) and the devices: SIP-compatible IP phones, supplied by us, included in the service or your own, and a SIP softphone of your choice on computers and smartphones. If the instance is in the cloud, no server is needed on site; if you prefer on-premises, we install it at your premises. If we already manage your firewall and network, QoS and security are already in our hands.
Teams Phone suits companies that already work inside Microsoft 365 and Teams all day and want full integration: telephony joins the same client, with presence, chat and meetings, and calls to the public network go through an operator or Microsoft calling plans. 3CX suits companies that already have it in house or want a commercial licensed platform, bought directly from 3CX or one of its partners, which also integrates with Microsoft 365. In every other case our Asterisk-based PBX is the most flexible and independent choice. We decide together after analysing lines and call flows, not from a catalogue.
