From whom to buy a virtual phone number?

Question

Telephony

I want to transfer the office to IP telephony. The question arose from whom to buy a number? It is to buy so that with this number you can migrate from one telephony provider to another. Is it even possible?

Answer 1

Migration is possible if the provider from which you originally purchased the number can redirect telephone traffic via ip to another telephony provider, and that one will have the technical ability to accept it. In fact, almost all operators allow this. Another thing is that the numbering capacity does not migrate with you, and you will access the city through a new provider, to which your number will not belong and he will not be able to close your outgoing connection with your old phone number (in 90% of cases). With that caveat in mind, the answer you're probably interested in is no.

No, unfortunately, VoIP providers are not so technically developed.
