[2016-06-13 13:37:34] WARNING[17071]: chan_skype.c:3322 account_status_change: Account USER logged out due to an incorrect password or invalid Skype BCP account
The account could not log in due to an incorrect password. This could
be due to the password being incorrect or because the account was
not created by the Skype Business Control Panel by clicking 'Create business
account'. Please be advised that the account that administers the BCP will not
work, nor will normal accounts that have been invited by the BCP. To verify
that the account is a BCP account, log into the Skype website at
https://secure.skype.com/account/login with the account and verify that
there is a box at the top of the screen saying 'You are a member of a
Business Control Panel'. If that message isn't there, you will need to create
a user from the Business Control Panel by clicking 'Add Members' and then
'Create a business account'.
