Redirection And Configuration Server (Rcs) Bypass Via Option 43 - Aastra 9143i Series Release Notes

New features in release 2.6
Example
The following example illustrates the use of the " ^ " in the configuration files.
aastra.cfg
^sip proxy ip: pbx.company.com
^sip proxy port: 5060
^sip registrar ip: pbx.company.com
^sip registrar port: 5060
In the above example, if an Administrator indicates the " ^ " before the parameters in
the aastra.cfg file, and then loads the aastra.cfg file to the phone, these four parame-
ters are reset to their default values, even if the parameters were previously changed
on the phone.

Redirection and Configuration Server (RCS) Bypass via Option 43

In Release 2.6, DHCP Option 43 support has been extended to include 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 new sub-option code 3 has been defined that 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 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.
