Abstract: Measures, including methods, systems and non-transitory computer-readable storage mediums, for use in providing presence notifications on behalf of an endpoint that does not participate in presence notification are disclosed. In embodiments, the presence server receives notifications from a switch providing services to the non-participating endpoint relating to that endpoint's status from which presence can be determined. This information is processed using a dummy roster in order to send out notifications. The dummy roster may be created responsive to receiving a subscription to presence notifications for the non-participating endpoint.

Abstract: A method of determining trigger conditions for scaling a scalable unit of network function comprising identifying a primary set of metrics associated with usage of an instance of the unit of network function as a primary indicator of occurrence of a load state thereof, and determining usage points when the primary indicator indicates that the load state occurs. Deriving a secondary set of the metrics, different to the primary set, as a secondary indicator of occurrence of the load state of the instance at each of a group of one or more of the usage points when the primary indicator indicates that the load state occurs, and measured data corresponding to values of the metrics in the secondary set of metrics at each of the group of usage points. Storing a trigger condition for scaling the unit of network function based on the secondary set and the measured data.

Abstract: Certain examples described herein relate to configuring a call control context in a media gateway. The media gateway has a set of digital signal processors, each having one or more digital signal processor cores. The cores implement digital signal processor channels that are grouped into digital signal processor contexts. When a request to configure a call control context is received, certain examples described herein are configured to assign a set of digital signal processor contexts to process data streams associated with the call control context. In particular, certain examples described herein couple a first digital signal processor context to at least a second digital signal processor context using at least one digital signal processor channel in each of the first and second digital signal processor contexts.

Abstract: A method of providing failover processing between a first element and a second element in a data communications network, the method comprising configuring a first channel and a second channel between the first and second elements, the first and second channels comprising different physical data paths, receiving at the first element, via the first channel, first data signals representative of functioning statuses of the second element, the first channel being configured to allow a non-optimal, partly functioning status of the second element to be communicated to the first element; and receiving at the first element, via the second channel, second data signals representative of functioning statuses of the second element, the second channel being configured to allow a failed functioning status of the second element to be communicated to the first element; and conducting failover processing based on both the first and second data signals.
