When using a Lync server infrastructure it is possible to use Lync Phones without connecting them to a PC using the USB cable. Devices like the Polycom CX500, CX3000, Snom UC600 or Aastra 6725ip are just a few examples. Since these clients are not connected to the PC they have to get their configuration information somewhere else.
This information is retrieved by the clients using DHCP. In DHCP the following options are used:
- 001 UCIdentifier;
- 002 URLScheme;
- 003 WebServerFqdn;
- 004 WebServerPort;
- 005 CertProvRelPath;
- 120 UCSipServer;
- 042 NTP Server (Optional);
While it is possible to configure these options manually there’s a tool in Lync that will retrieve the appropriate information and configure DHCP for you!
