Lync Phone Edition Time Synchronization

In order to get Lync Phone Edition (LPE) to Synchrnize time you need either and SRV record that points to your NTP servers (which may be your domain controllers) or allow Internet connection to your LPE devices,
as LPE synchnronizes time using one of the following methods:

  1. Lync Phone Edition searches for an NTP server in Domain Name System (DNS)  , it looks for the SRV record  _ntp._udp. pointing to NTP Server
  2. If Lync Phone Edition cannot find the NTP SRV record, it will attempt to use http://time.windows.com as an NTP server by searching for time.windows.com
so either create the SRV record or allow Internet access to time.windows.com on port 123 UDP.
