The connection between the IP Office and the Voicemail Pro services uses a password set in the IP Office security settings. When you change the password in the IP Office system's security settings, you must also change the password set in the voicemail server's preferences.
You can set the voicemail server preferences through IP Office Web Manager or using the Voicemail Pro client. Note that after changing the password, you do not need to restart the voicemail service. However, it may take a couple of minutes for the two systems to connect.
•For IP Office R11.1 FP1 and higher, the password for voicemail connection is enforced to 31 characters with restriction on repeated characters and enforcement of characters from different character types (lower case, upper case, numbers, extended characters).
