The following elements of the IP Office security settings affect installation:
•The one-X Portal for IP Office application uses the Enhanced TSPI service and EnhTcpaService user for its connection to the IP Office. The installation assumes that the EnhTcpaService user is enabled and has the default password of EnhTcpaPwd1.
•If the password is not at default during the Unified Communications Module installation, the one-X Portal for IP Office service will not start correctly and the service user account becomes locked. To resolve that, follow the steps below and then restart the one-X Portal for IP Office service.
•Once the one-X Portal for IP Office service is operating correctly, you can change the EnhTcpaPwd1 password.
•Voicemail Pro connects to the IP Office using the Voicemail Password. This is set in the IP Office system's security settings (System | Unsecured Interfaces) and must be matched by the password set in the voicemail servers preferences after installation.
