Consider the following scenario:
- An Enterprise Voice-enabled user signs in to Microsoft Lync for Mac 2011 in a Lync Server 2010 environment.
- The user calls a Public Switched Telephone Network (PSTN) number.
- The early media on the PSTN gateway is turned off in the environment.
This issue occurs because a local ring-back tone is not generated when the caller makes an outbound call through PSTN in Lync for Mac 2011.
