IVR
From FloristWiki
If you have Wireless Delivery Confirmation, you can use IVR (Integrated Voice Response). IVR allows you to mark orders Delivered or Not Delivered using ANY cellular phone that has caller ID enabled. First you must set up a cellular phone as a SmartTalk IVR device on the Gearworks Web site. Then using that phone, call a phone number to activate the IVR account. Then using your employee PIN number (generated on the Gearworks Web site), you can call from ANY phone (with caller ID) to log in and retrieve orders.
