A method is disclosed which allows an invitee to a conference call, who is not present on at least part of the call, to have the call monitored in his or her absence. The invitee is offered the opportunity to review, ahead of the call, one or more electronic documents that are pertinent to the call. The invitee can specify one or more pointers for the purpose of identifying positions that correspond to portions of the document that are relevant to the invitee. When a relevant portion of an electronic document has been reached or is soon to be reached during the call, a message is transmitted to the absent invitee. Additionally, the invitee can annotate slides or portions of an electronic document with comments that he or she wants addressed during the conference call. A message is subsequently transmitted to the invitee, providing responses to the comments left earlier.
