We have a Unity VM only installed with g729 only(all calls, prompts and recordings G729). Customer reports that once a caller records a message the system does not recognise the silence as the end of the msg - it therefore does not give any further options, just records silence. Are there isssues with G729 silence detection? Any workarounds? Unity 4.21, CCM4.1
