# Release v0.7.3 > Release Date: Feb 11, 2022 #### New Features - Adds support for redis authentication (via JAMBONES_REDIS_USERNAME / JAMBONES_REDIS_PASSWORD env vars). - Adds support for voice activity detection to `gather` and `transcribe` verbs: if activated, the connection to the speech recognizer will be delayed until speech has been detected. (In some deployments this can save on costs). - When using the `dial` verb with multiple targets, you can specify different custom headers to be used on a per-target basis. - Adds `overrideTo` property to `dial` verb to allow an outbound call to be placed to a registered user, but provide a different user or extension on the outbound invite. This can be useful for PBXs that register with jambonz under a certain user but can accept calls to a number of different phone numbers or extensions. - Adds fs_sip_address and api_base_url in webhook payloads; this aids in troubleshooting and can simplify the coding of webhook apps that also want to use the REST api. - Adds fs_public_ip to webhook payload when running in ec2 autoscale group. #### Bug fixes - Fixes memory leaks resulting from not closing speech synthesizer connections properly. - Fixes race condition on hangup that caused duplicate call-status webhooks. - Fixes race condition on hangup that sometimes resulted in outbound call attempt even though caller had hung up. - Adds missing Azure regions to jambonz portal for speech credentials. #### Availability - Available now on AWS Marketplace - Deploy to Kubernetes using [this Helm chart](https://github.com/jambonz/helm-charts) **Questions?** Contact us at support@jambonz.org
