Method for Authenticating Client Devices for a Conference Call

1 . A method for authenticating client devices from a conference call server, the conference call server including a memory for storing conference call scheduling information with respect to scheduled conference call sessions, wherein the conference call server is in communication with an enterprise server, the method comprising:

receiving in the conference call server a communication from a client device with respect to a scheduled conference call session; and

determining whether the client device is associated with the enterprise server, and if so authenticating the client device with respect to the scheduled conference call session.

2 . The method as claimed in claim 1 further comprising, after the authenticating, establishing a media session between the conference call server and the client device.

3 . The method as claimed in claim 1 wherein the enterprise server includes a registry of client devices, wherein the determining includes determining whether the client device is registered with the enterprise server.

4 . The method as claimed in claim 1 wherein the conference call scheduling information further includes a list of eligible participants each identified by an address which correspond to eligible client devices for the scheduled conference call session.

5 . The method as claimed in claim 1 wherein the determining includes determining whether a persistent unique identifier of the client device is associated with the enterprise server.

6 . The method as claimed in claim 1 wherein the communication is triggered from an option to select an address link selected from the client device.

7 . The method as claimed in claim 1 further comprising sending from the conference call server to the client device, after authenticating and in response to the communication, at least some of the conference call scheduling information including information for connecting to the scheduled conference call session.

8 . The method as claimed in claim 8 wherein the at least some conference call scheduling information includes password information for access to the scheduled conference call session.

9 . A conference call server comprising:

a memory for storing conference call scheduling information with respect to a scheduled conference call session;

a communications subsystem for communicating with an enterprise server and a client device; and

a controller configured for:

receiving a communication from the client device with respect to the scheduled conference call session, and

determining whether the client device is associated with the enterprise server, and if so authenticating the client device with respect to the scheduled conference call session.

10 . The conference call server as claimed in claim 9 wherein the controller is further configured for, after the authenticating, establishing a media session between the conference call server and the client device.

11 . The conference call server as claimed in claim 9 wherein the enterprise server includes a registry of client devices, wherein the determining includes determining whether the client device is registered with the enterprise server.

12 . The conference call server as claimed in claim 9 wherein the conference call scheduling information further includes a list of eligible participants each identified by an address which correspond to eligible client devices for the scheduled conference call session.

13 . The conference call server as claimed in claim 9 wherein the determining includes determining whether a persistent unique identifier of the client device is associated with the enterprise server.

14 . The conference call server as claimed in claim 10 wherein the communication is triggered from an option to select an address link selected from the client device.

15 . The conference call server as claimed in claim 9 wherein the controller is further configured for sending from the conference call server to the client device, after authenticating and in response to the communication, at least some of the conference call scheduling information including information for connecting to the scheduled conference call session.

16 . The conference call server as claimed in claim 15 wherein the at least some conference call scheduling information includes password information for access to the scheduled conference call session.

17 . A non-transitory computer readable medium having recorded thereon statements and instructions for execution by one or more devices for authenticating client devices for a conference call, said statements and instructions comprising code means for performing the method as claimed in any one of claims 1 to 8 .

18 . A mobile communication device comprising:

a controller;

a communications subsystem for communicating with a conference call server, wherein the conference call server includes a memory for storing conference call scheduling information with respect to a conference call session, the communications subsystem being configured for receiving a message containing sender information and an address link with respect to the scheduled conference call session;

a display for displaying an interface including an option to select the address link; and

wherein, in response to selection of the option through the interface, the controller controls the communications subsystem to send a communication to the conference call server, the communication being for receiving from the conference call server in response at least some of any remaining conference call scheduling information including information for connecting to the scheduled conference call session.

19 . The mobile communication device as claimed in claim 18 , wherein the message excludes the any remaining conference call scheduling information.
