Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, see HDX RealTime Optimization Pack 2.3 on the Citrix Product Documentation site.

New Fixes in This Release

1. With the HDX RealTime Optimization Pack installed, when a call is established between a Plantronics Calisto P240 handset phone and a Polycom CX300 desktop phone running on either 64-bit Red Hat Enterprise Linux 6.8 or 64-bit CentOS 6.9, the HDX RealTime Optimization Pack might pick up extra digits while dialing an extension. As a result, the wrong extension number is dialed.

2. When a call is established, the audio quality might be poor in fallback mode.
