Your professional phone system, hosted in France

What is a hosted VoIP phone system?
A business phone system (IP PBX) receives your company's calls and routes them: internal extensions, transfers, voice menu, call queues, voicemail. With VoIP, these calls travel over the Internet instead of a traditional phone line. When hosted, the phone system no longer runs on a box in your office: it runs on a server in a datacenter, and your phones connect to it from the office, from home or on the move.
- No phone equipment to install or maintain on your premises
- Extensions reachable at the office, when working from home or on the move
- Your numbers kept through number porting
- Capacity that grows with your headcount, from one plan to the next

FAQ
Frequently asked questions
Where is this service hosted?
In our regional hosting facilities in Lyon-Vénissieux and Grenoble, operated by ASN Cloud. Your data stays exclusively in France.
What is the uptime target?
We target 99.9% uptime over the year, measured monthly.
What is a cloud-hosted 3CX?
A cloud-hosted 3CX is your 3CX phone system installed on our cloud infrastructure, with no server to manage on your premises. ASN Cloud hosts, backs up and monitors your 3CX virtual machine in our hosting facilities in Lyon-Vénissieux and Grenoble: you access your business telephony from anywhere. Updates to the 3CX application are carried out by you, or by ASN Cloud under a managed services contract (on request).
Is your hosted 3CX sovereign?
Yes. Your sovereign 3CX is hosted exclusively in France, in our hosting facilities in Lyon-Vénissieux and Grenoble, under French jurisdiction and shielded from extraterritorial laws such as the Cloud Act. Unlike a cloud 3CX operated by a foreign hyperscaler, your communications and telephony data stay on national soil, operated by ASN CLOUD.
What exactly is 3CX?
3CX is a SIP-based software solution for business phone systems (PBX). It lets you manage your VoIP calls, traditional PSTN lines, video conferencing and team messaging from a single platform, accessible via browser, desktop and mobile apps. Your users get internal extensions, call transfers, voice menus (IVR) and call recording.
Is the 3CX license included in the price?
No. Our plans cover the hosting of the 3CX solution (dedicated VPS, OS, network infrastructure, backups, anti-DDoS) but not the 3CX software license itself. A free 3CX edition is available for up to 10 extensions, limited to SIP providers listed by 3CX. Beyond 10 extensions, or to use the ASN Cloud SIP trunk or the provider of your choice, a paid licence is required (BASIC, PRO or IA depending on your needs, at https://www.3cx.fr/commander/tarifs/). The customer chooses and purchases their license separately.
Can I port my existing phone numbers?
Yes. Number porting is requested from the provider of your SIP trunks: ASN Cloud, which offers SIP trunks on request, or the SIP provider of your choice. Your numbers stay the same, only their routing changes, independently of the hosting infrastructure.
Do you provide SIP trunks?
Yes. ASN Cloud offers SIP trunks on request, in two plans: unlimited calls to landlines and mobiles in France, or 50 destinations to landlines. You remain free to connect your 3CX to the SIP provider of your choice. As the free 3CX edition is limited to SIP providers listed by 3CX, a paid 3CX licence is required to use the ASN Cloud SIP trunk or the provider of your choice.
How many concurrent calls does each plan allow?
Studio: 8 concurrent calls, Office: 16, Business: 48, Enterprise: 100. The number of concurrent calls sizes the machine hosting your 3CX; the number of extensions depends on your 3CX licence.
How many extensions can I configure?
The number of extensions depends on the 3CX license you choose from 3CX, not on the hosting plan. The free 3CX edition supports up to 10 extensions, limited to SIP providers listed by 3CX. Beyond that, or to use the ASN Cloud SIP trunk or the provider of your choice, the 3CX BASIC, PRO or IA subscriptions unlock more extensions and features depending on the tier. Our hosting plans size the infrastructure (CPU, RAM, concurrent calls) to handle the corresponding load.
Is there a minimum commitment period?
No, our 4 3CX VoIP plans come with no commitment and monthly billing. You can change plans or cancel at any time from your customer portal.
What is the provisioning lead time?
The dedicated VPS with 3CX preinstalled is delivered within 24 to 72 business hours after order validation, depending on the plan chosen. You receive your SSH credentials, the 3CX administration URL and the initial logins by email.
Are there mobile apps?
Yes. 3CX provides iOS and Android apps as well as a web client: your staff make and take business calls from their smartphone or browser, at no extra hosting cost with ASN Cloud.
Is my phone system data backed up?
Yes. The entire virtual machine is backed up every day and each backup is kept for 7 days: 3CX configuration, call recordings and voicemail included, as they were on the date of the backup.
What level of support do you offer?
Our plans cover support for the hosting infrastructure: VPS, Debian OS, network, daily backups, anti-DDoS protection and delivery of a VM with 3CX pre-installed. Support for the operation, use, configuration and administration of the 3CX solution (extensions, IVR, call queues, SIP trunks, CRM integrations, user training, application troubleshooting, etc.) is not included in these plans: it is the responsibility of the customer, their certified 3CX consultant or paid 3CX support. As an option, an ASN Cloud managed services contract covers 3CX updates and support, on request.
Who configures and administers the 3CX solution?
ASN Cloud delivers a VM with 3CX preinstalled and provides the initial access credentials at order time (SSH root + 3CX administration URL). From there, full 3CX administration (creating extensions, configuring SIP trunks, setting up IVRs and queues, managing users, application backups, 3CX updates, etc.) is your responsibility or that of your 3CX consultant. Our commitment covers the proper operation of the underlying infrastructure (VPS, OS, network, anti-DDoS, system backups). As an option, an ASN Cloud managed services contract (on request) takes care of 3CX updates and support; any other work on the 3CX application can also be entrusted to a certified 3CX partner.
