no, phone numbers "take you" to index lookup in the SS7 system, which might direct a call to a DID hosted by a voip operator, a DID connected to an ESS5 switch serving POTS/analog dialtone customers, a DID connected to a fractional DS3 and somebody's legacy PBX, or to a mobile phone network and an IMEI.

by no means does a phone number mean that it must always go to a mobile phone network.
