We are installing a Partner ACS 5.0 system with Mail VS. This system is used for both company and personal communications. The system has been configured with extensions from 10-19 for business operations and extensions 20-35 for personal use. We are using an AA to answer the business calls but it seems that users can user a *8 to allow any extension to be called. We want to prevent the AA from allowing transfers to extensions 20-35. Is there a method to block this function or connection to particular extensions?
