Having created a module to re-record the auto-attendant prompt (Setting Up the Recordings Module), we need to be able to call the module. This can be done by adding a short code for the module.
In IP Office Manager, add the following system short code:
In Code, enter *80.
In Feature, enter Voicemail Collect.
In Telephone Number, enter "Recordings".
In Line Group ID, enter 0.
Save and merge the configuration to the telephone system.
Dial *80 from any extension.
Enter pin 1234.
Press 1. You should hear the existing auto-attendant announcement and then options to change it if necessary.
