Internet Telephony Service Providers

Buy Virtual Numbers provides Direct Inward Dialing (DID) access numbers (sometimes referred to as virtual numbers) and associated services to their customers on a world-wide basis.

Any of our virtual numbers can be forwarded to any of these Internet Telephony Service Providers.

ITSP (Internet Telephony Service Provider) is a provider of VOIP Telephone service. ITSPs are also known as VoIP Providers.

VoIP (Voice over IP) is a home phone service over your internet connection. VoIP gives an ability to transmit more than one telephone call over a single broadband connection. It is location independent service, because only a sufficiently fast and stable Internet connection is needed to get a connection from anywhere to a VoIP provider. Also it can be a benefit for reducing communication and infrastructure costs.

Monthly price: 0.00 USD

Interruption of PBX phone.systems service

By December 31, 2022, the PBX phone.system will be discontinued.

Although, until that date, phone.systems will still work for the DID numbers that are already using it, it is no longer possible to forward new numbers to phone.systems.

If you are currently using phone.systems, you can still use phone.systems until the end of the year, however you are recommended to change the call forwarding to a third party VOIP account or to a PSTN number before that date.

You can find here a list of recommended and free VOIP providers that you can use to receive calls for free: Itsp-list

Due to this disruption, you will be no longer able to make outbound calls with our system. However, you are authorized and invited to use, for this purpose, other VOIP services available on the market (for example, Dellmont providers), by registering our DID numbers as caller IDs.

We sincerely thank you for the great success that our PBX has had thanks to you in these years, and we apologize and are deeply ashamed for having been forced by our supplier to stop this service, despite our repeated invitations that we have addressed to him to desist from this decision.

Important: The break is only related and limited to phone.systems. None of the other services are affected: in particular it will be possible to receive calls on a VOIP server or on a PSTN number. The SMS receiving service is also not affected.
