Abstract: Initiating a conference call includes receiving a conference call request message from an initiating user specifying a plurality of other users and determining an availability of the other users to receive conference call invitations. A conference call is initiated between the initiating user and one or more of the other users that are determined to be available. The availability of one or more of the other users determined to be unavailable is monitored and interaction with a conference call invitation by one or more of the other users determined to be unavailable is enabled upon their monitored availability changing from unavailable to available. The interaction with the conference call invitation by the other users is conditioned on whether the conference call is still in progress.

Abstract: Audibly informing a recipient of an arrival of a digital communication from a sender includes receiving a digital communication from a sender directed to a recipient and determining whether the digital communication is associated with an audio identifier that identifies the sender of the digital communication and that is designated by the sender of the digital communication. Perception by the recipient of the audio identifier is conditioned on whether the digital communication is determined to be associated with the audio identifier. The audio identifier is perceived prior to or concurrent with perception of the digital communication by the recipient.

Abstract: Enabling a recipient to control presentation of an audio identifier informing the recipient of an arrival of a digital communication from a sender in a communication session includes receiving a digital communication from a sender directed to a recipient. A sender-designated first audio identifier or sender-related information that identifies the sender to the recipient is accessed upon arrival of the digital communication. The first audio identifier or sender-related information is presented to the recipient contemporaneous with receipt of the digital communication. The recipient is able to specify, upon presentation of the first audio identifier or sender-related information, whether to enable subsequent presentation of the first audio identifier prior to or concurrent with receipt of a future digital communication from the sender.

Abstract: A first user's avatar in a virtual world environment may be controlled by using a virtual world application enabling access to a virtual world environment within which the first user has an avatar associated with the first user. A virtual world location corresponding to the first avatar is identified. At least one second avatar proximate to the virtual world location is identified. Filtering information is accessed. Profile information related to the second avatar is accessed. Filtering information is compared to the accessed profile information. Based on the comparison results, a metric related to the second avatar is determined. The metric is related to a threshold. It is determined whether relating the metric to the threshold supports enabling communications between the first and second avatars, and if so, communications to be exchanged between the first and second avatars are enabled.

Abstract: Alerting an intended recipient of a phone call includes identifying an account based on a phone call received from a caller and accessing configuration data related to the account. The configuration data is used to identify an identity associated with the account. One or more external online service provider systems are queried across a network to determine whether the identity is available to receive an electronic communication associated with the phone call. The electronic communication associated with the phone call is sent across the network to the one or more external online service provider systems conditioned on whether the identity is determined to be available to receive the electronic communication. The one or more external online service provider systems send the electronic communication to the identity.

Abstract: Audibly identifying an event includes enabling selection of a first sound based upon an identifier. The identifier enables identification of an entity related to the event. A notification of an occurrence of the event is received. The notification includes the identifier. An intended recipient is alerted of the event by playing, in response to the notification, at least a portion of the first sound and at least a portion of a second sound that is related to the event.
