Cisco Jabber for Windows Not Connecting to Voice Mail
Under File -> Options -> Phone Accounts -> Voicemail, getting "Invalid username or password"
If no Voicemail section is being displayed, then on CUPS Admin Page -> Application -> Jabber -> Settings, "Credential Source for Voice Mail" is probably set to CUP
Cisco Jabber for Windows (CUPS Deployment)
User entering AD Password instead of Web Application password (If uses in UC are not integrated with LDAP)
If users in UC are not integrated with LDAP, when you goto UC Admin Page -> Users -> Settings -> Change Password, from the drop down, you'll notice "Web Application" password. Reset that and enter that in Cisco Jabber Voicemail Credentials section.
If User is integrated with LDAP and it still fails, then OS Secure Mode is probably set to Enforcing on Unity Connection
This will result in Defect CSCty05524 "UC 220.127.116.1109-1 IMAP Authentication failed when using LDAP directory."
Then to resolve this
Switch the SELinux mode to permissive using the following CLI command:
utils os secure permissive
Upgrade to the last version of CUC as it has been fixed in version 18.104.22.16800.5
Restart IMAP Server on UC
CSCty05524 "UC 22.214.171.12409-1 IMAP Authentication failed when using LDAP directory."
