Grandstream WP820Version 1.0 20210823 Tested on firmware 1.0.7.50 Note that when the phone configures it will set the server IP as its location to pull configuration files from and disable option 66. This way option 66 can be changed later and the phone will continue to pull configuration from the server. Phone will check daily for new configurations in between the hours of 1 and 3am. Note the digit map must be entered inside curly brackets (i.e. { 3xx | 4xx} otherwise it will not work and the default will remain in use. Note also that things outside the digit map can’t be dialed.
