Key features of UCMA 5.0

  • Article

Applies to: Skype for Business 2015

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

Modality-extensible communication framework

  • 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, gateway interoperability and other operations).

  • Integrated audio devices: recorder, player, tone controller for Dual-Tone Multi-Frequency (DTMF) and Fax tones, 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 platform to handle a new media type by creating custom Call, MediaProvider, and MediaFlow subclasses that work with the new media type.

Offline conference scheduling and management

  • Conference retrieval from PSTN conference ID.

Presence publishing and presence subscription

  • Publishing framework based on presence manifest. The manifest is predefined in UCMA 5.0 and follows the same rules for presence publication as Skype for Business 2015.

  • Automatic user endpoint bootstrapping based on container manifest.

Contacts and groups

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
