Key Features of UCMA 2.0 Core SDK

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

Developers can use the key features listed in this topic to create multimodal and multiparty communication and collaboration applications with Enhanced Presence capabilities.

  • Integrated support for Instant Messaging (IM)

  • Integrated support for audio, with Secure Real-time Transport Protocol (SRTP), early media, and multiple codec selection

  • Common telephony features enabled by means of a reusable signaling framework (transfers, forwards, caller on hold, and other operations)

  • Integrated audio devices: recorder, player, tone controller for Dual-Tone Multiple-Frequency (DTMF), and connectors for speech recognition and speech synthesis

  • Loose coupling between signaling and media, allowing back-to-back and scenarios such as media-enabled Web clients

  • User impersonation

  • Conferencing features (control and monitoring): anonymous user join, trusted user join

  • Multimodal escalation-to-conference helpers for instant messaging calls

    Developers who implement a custom audio provider can provide support for escalation-to-conferencing for the custom media type.

  • Platform extensibility by means of the factory-based Call and MediaProvider classes

    Developers can extend the UCMA 2.0 Core SDK platform to handle a new media type by creating custom Call, MediaProvider, and MediaFlow subclasses that work with the new media type.

  • Conference retrieval from PSTN conference ID

  • Publishing framework based on presence manifest

    (Note that in the UCMA 2.0 Core SDK the manifest is predefined, and follows the same rules for presence publication as Office Communicator 2007.

  • Automatic user endpoint bootstrapping based on container manifest

The following features apply only to UserEndpoint type, not the ApplicationEndpoint type.

  • Contact object registration

  • Contact list creation and management

  • Contact organizations in provided or custom groups
