Region-based connecting of calls using client-specific control and provisioned numbers

A method involving use of a data communications apparatus involving a communications provider server to communicate data and provide data communications services to a plurality of disparate client entities, each including a respective client data-communications server and each including a processing circuit, the method comprising:

• via the respective client data-communications server of at least one of the plurality of disparate client entities, controlling communication between endpoint data-communications devices respectively associated with said at least one of the plurality of disparate client entities;
• via the processing circuit associated with said at least one of the plurality of disparate client entities, communicating with the communications provider server via sharing of client-specific sets of data indicative of client-specific communications routing information and/or client-specific communications data, wherein the communications provider server and each of the plurality of disparate client entities are to facilitate permissible types of communications;
• and
• wherein the processing circuit communicates with the communications provider server by:
• sending a data packet for a first port of the communications provider server and therein requesting a data communications call based on a determination of a geographic region that an endpoint device identified using the data packet is located;
• providing information from which the communications provider server is revise a caller identification (ID) for the data communications call based on the determined geographic region, on the client-specific sets of data, and on an identifier that corresponds to one of the endpoint data-communications devices, from among the endpoint data-communications devices, requesting the call;
• and
• permitting connection of the call via a provisioned connection number, the provisioned connection number including the revised caller ID that includes a local number identified by the determined geographic region.
