determining that the mobile device if the mobile device does not comply with the access requirements; in response to the determining that the mobile device does not comply with the access requirements, rejecting the mobile device; in response to rejection the mobile device, determining by a processor based on information other than said access requirements that the mobile device is legitimate; and in response to the determining that the mobile device is legitimate, overriding the rejection to allow connection to the conference call. ### Claim 2 (depends on 1) The method as defined in claim 1, a notification of the rejection being received by a moderator of the conference call. ### Claim 3 (depends on 1) The method as defined in claim 1, a notification of the rejection being received by a participant of the conference call. ### Claim 4 (depends on 1) The method as defined in claim 1, the other information being received by a moderator. ### Claim 5 (depends on 4) The method as defined in claim 4, the other information being an email received from a rejected participant. ### Claim 6 (depends on 1) The method as defined in claim 1, including a moderator using an address book to determine the request is legitimate. ### Claim 7 (depends on 1) The method as defined in claim 1, instructing a calling device to fetch a rejected participant. ### Claim 8 (depends on 1) The method as defined in claim 1, including generating a log of all requests to participate. ### Claim 9 (depends on 8) The method as defined in claim 8, the log including credentials of rejected participants. ### Claim 10 A mobile device for controlling access to a conference call, the mobile device comprising: a communications platform; and a processor, the processor and communications platform configured to: authenticate a requesting mobile device in accordance with access requirements for the conference call; determine that the requesting mobile device does not comply with the access requirements; in response to the rejection, determine based on information other than said access requirements that the requesting mobile device is legitimate; and override the rejection to allow connection to the conference call if it is determined that the requesting mobile device is legitimate. ### Claim 11 (depends on 10) The mobile device as defined in claim 10, including a log for storing credentials of all participants being authenticated. ### Claim 12 (depends on 10) The mobile device as defined in claim 10, including a log for storing credentials of the rejected participants. ### Claim 13 (depends on 11) The mobile device as defined in claim 11, a notification of the rejection being an email. ### Claim 14 (depends on 10) The mobile device as defined in claim 10, the override being generated by a conference call moderator device.
