Voice call continuity is provided for calls that are carried over a hybrid network infrastructure in which access connections are distributed over loosely coupled network portions including a backend network such as a core VoIP (Voice over Internet Protocol) service network, one or more cellular mobile networks, and a public switched telephone network ('PSTN'). The calls are routed through the core VoIP network regardless of their points of origination or termination in other network portions so that signaling and call context are anchored in the core VoIP network. The conditions under which user equipment operate are continuously monitored so that when a connection is determined to have been unacceptably degraded or is likely to be interrupted, and/or a more optimal connection is available, a handover of the call to another connection is initiated so that call continuity is maintained using the lowest cost connection that provides acceptable call quality.

The claimed subject matter provides a system and/or a method that facilitates enhancing real time unified communications. An interface can receive a portion of data associated with at least one of a client application or an environment that hosts a client application. A real time collaboration (RTC) component can employ an RTC file package to seamlessly initiate a real time collaboration session with the client application, wherein the RTC file package can include a portion of data that relates to at least one of the client application, the host environment, or a modality of the client application.
