ABSTRACT:
A method and apparatus for establishing a voice call to a PSTN extension on behalf of a networked client computer, and routing the voice call off of the network, is provided. In a first embodiment, the apparatus comprises a storage medium having stored therein a plurality of programming instructions for implementing a set of communication services for facilitating establishment of the voice call to the PSTN extension, and an execution unit, coupled to the storage medium, for executing the plurality of programming instructions. The set of communication services include services for soliciting inputs from one or more other apparatuses on one or more operating characteristics associated with the establishment and support of the voice call to the PSTN extension, and selecting either the apparatus itself or one of the other apparatuses to place the voice call to the PSTN extension.
