Does the RPS accept variables?

Doesn't seem like it does to me. I'm new to Yealink handsets, but then I read in the Autoprov guide that you can hand out $PN and $MAC to phones in a URL - however, this is only for an address handed out in a DHCP Option that the phone then substitutes those variables.

When I added $MAC into my RPS server URL it did nothing and interpreted it as a directory, when the phone came looking on my server it was looking for /$MAC/<mac_addr>.cfg
