Number Hosting
An advanced solution for voice management
Number Hosting is a Professional Link service provided in collaboration with Connecting Project that allows telecommunications operators to manage their telephone numbers even without a direct connection to Telecom, maintaining their identity and independence.
Professional Link offers a wide range of electronic communications services, including telephone traffic termination services for national, international, and non-geographic numbers.
In the current telecommunications environment, reliability and regulatory compliance are essential. Our Number Hosting service was created with the aim of offering operators a solid, transparent, and highly professional model capable of meeting these needs.
What is Number Hosting
Number Hosting is a service provided in Italy by Professional Link and the company Connecting Project. It allows Telco operators that do not have a direct interconnection with the TIM network to manage and control their number ranges, taking advantage of Professional Link’s voice network and the consulting expertise of Connecting Project.
FVNO: a new model of fixed-line telephony
The Fixed Virtual Network Operator (FVNO) paradigm introduces an innovative approach to fixed-line telephony management. It is designed for Telco operators who wish to develop or consolidate their voice offerings without undertaking complex infrastructure investments.
Thanks to this model, it is possible to:
- Have proprietary geographical numbers
- Operate completely independently
- Ensure regulatory compliance
- Rapidly scale your business
- Offer advanced and secure voice services to end customers
All of this without having to manage the technical, regulatory, and operational challenges associated with the industry. In the proposed solution, infrastructure, technology platforms, and compliance management are integrated.
National carrier tools without carrier costs. Operators get to do things differently now.
Who is it for?
Number Hosting is designed for:
- Switchless operators with a customer base evolving towards structured voice services
- Switched operators with non-compliant or non-interconnected infrastructures
- Voice resellers looking to offer voice services in a professional, scalable, and cost-effective manner
The model is suitable for both those who already have infrastructure and those who want to quickly launch an offering without significant initial investment.

Who is it for?
The first digit of each number range (called a “code”) specifically identifies the services that can be provided within that number range. These “codes” can be considered “number ranges.” Number ranges are blocks of telephone numbers assigned to telephone operators. These ranges can include geographical, non-geographic, and mobile numbers. Number Hosting enables the number ranges assigned to a given operator to function. In Italy, the Italian Communications Regulatory Authority (AGCOM) establishes which numbers are allocated to the various services, while the Ministry of Economic Development (Communications Department) assigns them to applicants.
What are the technical details?
Professional Link combines Number Hosting with Telephone Number Management on our proprietary infrastructure, including interconnection services. This allows telephone operators to provide voice or VoIP services to their end customers. With Number Hosting, PLINK hosts on its network the geographical number range owned by the host operator wishing to provide telephone service to its customers.
Telephone traffic termination can be performed at:
- National Geographic Numbers
- International numbers
- Non-geographic numbers (mobile numbers, toll-free numbers, and numbers for premium-rate services)
Should I purchase a softswitch or invest in voice infrastructure?
No. The service includes the entire technical architecture, already virtualized and in production.
- Cirpack softswitch compliant with ST.763xy and ST.769,
- SBC routing, porting out, DB-MNP,
- Compliance and anti-fraud modules,
- Integrated billing systems.
How are geographical numbers managed?
Professional Link assigns geographic numbers registered to you, as required by law, managing the entire relationship with TIM and the configuration of the system plan. The use is entirely yours: you activate, change, and deactivate the numbers directly from the SYD portal.
I am required to manage regulatory compliance myself?
No. The platform is designed to be compliant by design, already compliant with:
- ST.769 and ST.763xy for routing and signaling.
- CLI Screening and Portability.
- ETSI lawful interceptions,
- Data retention and CDR management via cook_cDR,
- DCPR (ETNA, NUE, DBU).
No additional adjustments or investments are required on your part.
How does Fraud Protection work?
Each number can have customized thresholds.
- minutes/hour
- number of calls/hour
- Destinations
- Time and risk bands
When the threshold is exceeded, the system automatically blocks the affected number and sends alerts via email, SMS, or Telegram. This protects your margin and that of your customers in real time.
Can I manage everything independently without opening tickets?
Yes. The SYD portal is designed to give you complete independence. It allows you to:
- Activate/change/terminate VoIP accounts.
- Manage NP and port out.
- Monitor diagnostics and traffic.
- configure anti-fraud,
- Manage billing and rate plans.
Is it possible to enhance traffic without purchasing a billing system?
Yes. The platform includes the Money module, which allows you to:
- Manage postpaid and prepaid (not in real-time),
- Apply price lists, minutes, and promotions.
- Generate cost, revenue, and margin reports.
- Integrate data into your accounting and management systems.
- The system already includes a professional billing system.
How long does it take to activate the service?
The infrastructure is already active. The timeframe depends mainly on the initial configuration, the operator onboarding process, and any migration of existing numbers.
We can evaluate this together during a meeting to assess your situation. Book a personal meeting with the PLINK team
Professional Link and Connecting Project: what role does each have?

For you, there’s a single point of contact: Professional Link.
How much does the service cost?
Costs depend on the operator’s profile (switched, switchless, reseller) and volume.
