You should do this using an "a=" line -i.e.
         a=<parameter-name>: <parameter-value>

<parameter-name> should begin with "x-", to indicate that this is just an 
experimental parameter name (that you're choosing), rather than a standard 
one that's defined in a RFC.

Of course, you will also need to modify your client code to recognize and 
handle your special parameter name.
