I should have been clearer, the OP doesn't want "analog" service but PSTN (TWM switched) service. Unfortunately that is dying out as carriers are moving to all IP core networks. As customers have moved away from fixed landline service it ends up costing more per customer to keep the PSTN running. The last mile equipment is the same for TWM or IP switching but they can dump that directly into an IP network rather than maintain a hierarchy of COs/tandems/toll switches with dedicated links between them.
