The server's fully qualified domain name can include the path to a subdirectory of the
server root, such as "http://myserver/teoupdates/7810".
Alternatively, you can use the UpdateSrvr parameter in vendor-specific DHCP Option 125
to configure this parameter. In addition, Option 125 allows you to set VLAN and other
parameters that may be sufficient to configure phones without an update server.
NOTE: To avoid conflicts, do not set update server parameters in both Option 66 and
Option125.

Enter either an IPv4 address or, preferably, a DNS fully-qualified domain name as a string
value to be used by the SIP client to locate a SIP proxy server.
Alternatively, you can use the SipProxyServer parameter in vendor-specific DHCP Option
125 to configure this parameter. In addition, Option 125 allows you to set VLAN and other
parameters that may be sufficient to configure phones without an update server.
