A work-at-home telecommunication service is provided in response to receiving, from a calling party, a service-specific vertical feature code and a dialed number to initiate a call. The call is suspended and a query is sent to a service control point after receiving the vertical feature code and the dialed number. The query includes the dialed number and a calling party identification number. A response to the query is formed using the service control point by translating the dialed number to a called party identification number, and by modifying the calling party identification number to an identification number of a group associated with the calling party. The response includes the called party identification number, the calling party identification number, and a carrier identification code which identifies a telecommunication carrier for the group associated with the calling party. The call is routed to the called party using the telecommunication carrier identified by the carrier identification code. A distinctive ring can be provided at the called party to indicate that the call is associated with the work-at-home telecommunication service.
