Abstract: A user terminal, the user terminal comprising a communication client application for managing communications with at least one further user terminal over a first network, the communication client application being configured to: determine with respect to at least one outgoing call the first network is a lower bandwidth data network; generate an interrupt message to be displayed; determine a user input in response to the interrupt message; and manage a placement of the communications with the at least one further user terminal over the first network based on the user input.

Abstract: A computer system comprising one or more computer devices, the computer system providing a provisioning service of autonomous software agents (ASAs), the computer device comprising: a user interface generating component operable to provide a portal to a human user via a display, the portal having entry fields for receiving agent data from the human user; a storage interface component operable to access computer storage that stores autonomous software agents; and an access component operable to hold an association between the agent data and a network address of an agent, the network address defining a location of the computer storage in a computer network at which the agent is stored, whereby when an entity selects an agent based on the agent data, the access component enables automated access to the agent based on the network address.

Abstract: A method for managing and communicating network characteristic presence status information between user terminals, the method comprising: determining network characteristic presence status information associated with a first user terminal based on the receipt or absence of a network characteristic presence status update message; and communicating the network characteristic presence status information associated with a first user terminal to at least one further user terminal, such that the at least one further user terminal indicates the current network characteristic presence status associated with the first user terminal.

Abstract: A user terminal, the user terminal comprising a communication client application for managing communications with at least one further user terminal over a first network, the communication client application being configured to: determine with respect to at least one outgoing call the first network is a lower bandwidth data network; generate an interrupt message to be displayed; determine a user input in response to the interrupt message; and manage a placement of the communications with the at least one further user terminal over the first network based on the user input.

Abstract: A user terminal, the user terminal comprising a communication client application for managing communications with at least one further user terminal over a first network, the communication client application being configured to: determine with respect to at least one outgoing call the first network is a lower bandwidth data network; generate a bandwidth adaptation message configured to manage communications over the first network, such that a communications quality associated with the communications with at least one further user terminal over a first network is maintained at an acceptable level.

Abstract: There is provided a user terminal comprising: at least one processor; and a memory comprising communication client application code for managing communications with at least one further user terminal over a first network, the code, when executed on the at least one processor, causes the user terminal to: send a call request to the at least one further user terminal over the first network; if a call has not been established with the at least one further user terminal after a predetermined period of time, determine why the call has not been established; select a notification to be displayed to a user of the user terminal in dependence on said determination; and cause said notification to be presented to the user
