Option 43 Redirection and Configuration Server (RCS) Bypass
DHCP Option 43 includes the ability to bypass contacting Aastra's Redirection and Configuration
Server (RCS), in addition to the previous support of setting the configuration server to contact.
A sub-option code 3 uses a boolean value (true or false) that controls whether or not the phone
should contact the RCS after a factory default. If this value is set to false, the the RCS is not
contacted. If it is set to true or is missing, then the RCS is contacted as per previous releases. This
can be used in conjunction with the existing code 2 sub-option to set the configuration server.
