If you need a directory for your VoIP system, the most efficient way of doing this is sending over an excel spreadsheet to support@ice-comms.co.uk in the format of, Firstname, Lastname, Number, We can provide a template for this too!
Our team can then bulk upload or tell you how to do this for future reference and any changes needed. This will then apply the company wide directory to all handsets within the Horizon account.
