Although I haven't gotten there yet, the answer to the above question is in the guide the previous posters spoke of:
SET NVWEBLMURL http://
XX.XX.XX.XX:8080/WebLM/
LicenseServer
However, I am still stuck on one of the first and probably simplest steps... when I put a phone in group 876, and have the added snippet of code in the 46xxupgrade.scr file, the phone never goes to get the 46xxvpn.scr like it's supposed to (assuming its in that group).... how can I test or status to verify the phone is really in the group I think it is?
