Version 20.2.1

Resolved issues
This release fixes a number of issues to enhance the reliability and usability of the VidyoGateway. For more details, see the "Resolved Issues" section below.

You must upgrade to VidyoGateway version 20.2.1 from VidyoGateway version 20.1.0 or later. Therefore, if you have a VidyoGateway version earlier than 20.1.0, you must first upgrade to 20.1.0 and then upgrade to version 20.2.1. Please refer to the Upgrade a VidyoGateway 20.1.0 Cluster to Version 20.2.1 section below for more information. These steps must be done in order.
If you have installed a previous VidyoGateway version 20.2.1 beta, you should first downgrade your VidyoGateway to 20.1.0 using the Recovery Utility on the System Console, and then upgrade directly to the GA 20.2.1 version. For more information, refer to "Run the recovery utility" section of the VidyoGateway Administrator Guide.

VidyoGateway version 20.2.1 is compatible with VidyoPortal version 18.4.0 and later.

VidyoGateway Version 20.2.1 - resolved issues

XGW-675	Inbound calls no longer fail if endpointModel uses the "~" character.
XGW-674	When configuring a SIP proxy with an FQDN or IP, the SIP proxy FQDN/IP is now correctly appended as @domain to the dialed digits.
