1. A method comprising:

  • receiving, by a processor, a request from a first user to establish a second communication session with a second user, wherein said request specifies a maximum time duration of said second communication session; and

    determining whether to grant said request based on said maximum time duration and on presence information for said second user, wherein the determination whether to grant said request is also based on a calendar entry of a first communication session that includes a first end time of said first communication session, wherein said first end time of said calendar entry of said first communication session is modified to a second end time based on said second user terminating said first communication session before said first end time of said first communication session, and wherein said second request is granted based on said modified second end time.
