Mobility Entry allows you to access all of the features provided by your communications platform from your mobile phone or your portable home office phone. If Mobility Entry is activated, you can access the same communications platform functions that are available to you at an internal station without having to install additional hardware or software. All you need to do is dial your DISA phone number.
The FMC-Outlook Tool can be used for easy conversion of Microsoft Outlook contacts into the appropriate format. This tool frees the user from typing in the DISA prefix manually into phone book of his mobile phone or into his Microsoft Outlook contacts .
