# What's New for this Release

## Wi-Fi to Wireless Wide Area (WWAN) Network Handover

When on an active softphone call on a MiCollab Mobile Client, if the current network becomes unavailable, MBG supports the ability to move from Wi-Fi to WWAN to ensure the call continuity.

Note: For the WiFi to WWAN feature to work the MiCollab Mobile Client must be configured to connect to the same MBG whether it is using WWAN or WiFi.

Refer to the MiCollab documentation for additional information.

## Support for Mediasec in SIP Trunking

Enable mediasec for SIP Trunking to ensure SRTP is enforced on SIP Trunk connections between MBG and the SIP Provider.

## Support for Local and Bypass Streaming

MiVoice Business

Support for Local Streaming has been available on MiVoice Business for RTP, with MBG 11.5 SP1, Local Streaming for MiVoice Business for SRTP is available.

Configuration requirements for Local streaming have changed, see Engineering Guidelines for details.
