How does the migration proceed step by step?
The number transfer takes place between the receiving and releasing operators. As a customer, you submit a porting request to the new (receiving) operator; there is no need to apply to your current operator. The receiving operator then coordinates the entire process and manages the technical switch-over.
After the application is submitted, the transfer typically takes several working days. The exact duration depends on the type of number (landline or mobile) and whether all supporting documents are in order. The actual technical switch usually takes only a short time and is carried out outside peak hours, so service interruption is minimal.
What does refrigerant migration require and what should be watched out for?
For a trouble-free installation you need:
- Exact number format - number in the format registered with the original operator (usually including the area code).
- Compliance with contractual terms - if you are bound by a fixed-term contract, the operator may charge an early termination fee. This does not prevent porting.
- Proper documentation - an authorised person (for example, the company director) must sign the application.
Common complications arise when the number is not registered to the current owner or when the billing address differs from the number's registration. These discrepancies can slow down the process.
Connection to a virtual central control system: specific requirements
When switching to a virtual PBX, you port your number to the cloud telephony provider. The number then functions as an incoming line for the PBX. You can configure IVR, call forwarding, a call queue or an AI receptionist on it just like on any other number in the system.
When porting a fixed (geographic) number, it is necessary to ensure that the new operator accepts this type of number. On virtualni-ustredna.cz, support coordinates the number porting and guides you through the entire process from submitting the request to verifying functionality.
Frequently Asked Questions
Can I transfer both a mobile and a landline number?
Yes. Number portability applies to both fixed (geographic) and mobile numbers. The conditions and duration of the process may vary slightly depending on the type of number and the original operator.
What happens to the number during transmission?
The number remains active with the original operator until the moment of technical switching. The outage is usually brief and typically carried out outside peak hours to minimise impact on business operations.
Can the number be transferred back if I am not satisfied?
Yes. Porting is not an irreversible step. The number can be transferred again to another or the original operator under the same legal conditions.
