This release supports Edge Chromium (Microsoft Edge).

In earlier releases, Cisco VVB supported blind transfer as a way for VXML applications to transfer an IVR session to a required SIP endpoint. With this release, Cisco VVB adds bridge transfer capabilities to VXML applications. The bridge transfer implementation allows VVB to transfer an IVR session to a SIP endpoint (CUCM, agent, or third-party IVR) while maintaining control of the media path.

Bridge transfer in the connecting or connected state can be terminated by injecting single DTMF digit, as specified in the Call Studio bridge transfer term character. It is recommended that customers do not set term char if bridging to another IVR. The incoming and destination dial peer (or DN) cannot be of the same pattern as it applies to route hunt configured on CUCM.

Note	Bridge transfer is supported only with G711 u-law and G711 A-law. Bridge transfer supports only SIP URI. Bridge transfer does not support TLS/SRTP.

Cisco VVB now supports speech recognition and customers can now record the utterance of their speech operations.

With this release:

• The caching algorithm is optimized to provide faster access to the cached entries.

• HTTP Max-Age attribute is supported for caching.

• For Packaged CCE deployment model, customers can now use the Unified CCE Administration user interface instead of VVB AppAdmin for configuration and administration.

• NLU Support using Nuance: Cisco VVB is now compatible with Nuance NR11 that enables the AI IVR-based application based on Speech Recognition/NLU.

• Support for 2048-bit encryption: Cisco VVB now supports 2048-bit encryption.

• Enhanced Security: Cisco VVB now supports QoS for SIP and RTP.

• REST APIs for configuration and administration:

  • System Parameter Configuration API: Cisco VVB now supports configuring the system parameters for TLS/SRTP/ciphers using REST API.

  • Media Parameter Configuration API: Cisco VVB now supports configuring the media parameters for codec, MRCP version, overriding system prompts using REST API.

• Enhanced event handling.

• UUI/AAI handling in transfer scenarios.

• FetchAudio attribute for audio now supports loop and starttime attributes.

• Improvements in VXML 2.0/2.1 compliance.

• Support for transcription grammar.
