asterisk users - Dec 2005 - sipura "Vertical Service Activation Codes"

Do the Sipura "Vertical Service Activation Codes" have any meaning to
the phone itself?  It doesn't seem like they do anything, but that
leaves me with the question why are they listed at all?

I'm trying to reconcile asterisk's idea of some features like group
pickup being on "*8" with the sipura's desire to have it on
"*37".
Which one is more common these days?  Can I just make an extension
and assign the pickup code to it?

    exten => *37,1,pickup(SOMETHING_TBD);
