Hi. I'm brand new and must be missing something simple, but I had 3cx automatically provision two yealink t20p phones and it seems to have changed the password for one so I can not log into that phone's web page. Both phones originally had user. Name/password combos of admin/admin, and when I provisioned I put in admin everywhere I saw password (and specified an id of admin as well). That worked for one phone but the other lost its password or username. Where am I going wrong?
