To use webpro no license required just use Internet explorer other engines will not work or give errors. Phonepro is more if your offsite and want to change remotely. The biggest issue with webpro the phone will say (in program mode)while you are logged in if you do not log out in top right corner and just close the screen the phone will remain locked for about 15 minutes no matter how many times you reboot it still takes 15min.
