Skillset , Holiday greeting?
A holiday greeting table is scheduled and you program it to us a greeting table. Plus it only plays for 1 day.
Did they just program a company greeting and assign it to a table?
And to have all users DID's be answered by a greeting table would be pain in the you know what. You could set up a service mode with all the DID;s and the VM DN in a ring group, when active it will answer all calls. But the callers wont be able to leave a messing for the number,DID they are calling since it is being answered by the AA the caller will then have to dial the extension to get back to leave a message.
