AlterTEL Sp. z o.o.

AlterTEL has the internet identifiers of an operator, the Polish authorisations of a fixed-voice provider and the public presentation of a technical-service company. Those three identities meet in Warsaw, but they are not interchangeable. The commercial question is therefore unusually physical: when AlterTEL sells a business connection or an IP-telephony service, which part of the path can its own people restore, which part belongs to an upstream or building provider, and has the price allowed for the difference?
