Click the following link for details of setting up FrontlineSMS to use the IntelliSMS SMS Gateway
http://www.frontlinesms.com/help/settingsmenu.htm Here is the relavent information copied from this page: To use IntelliSMS you need to sign-up for an account on the IntelliSMS website. Once you have your user details you simply enter your username, password and the mobile number you used to register with the service - which should ideally be the number you plan to use in your FrontlineSMS system - into the
IntelliSMS Account Configuration screen, below.
If you want to also be able to receive text messages through the IntelliSMS service - a helpful option if you don't have a phone or modem to attach to your computer - you need to edit your
"My Account -> Preferences" options on the IntelliSMS website, adding your email address and setting the Forwarding type to Email (see below)
To finish, you now need to tell FrontlineSMS you want to receive messages via the service, and input your email account settings. You may need to consult your email service provider, or their website, to get some of this information, which needs to be added to the fields below in the
IntelliSMS Account Configuration screen. Tick the
Use for receiving box and enter your information (see example below)
TIP: It is recommended that you create a separate and dedicated email address for this service, and not use your personal email address
You should now be ready to go! If you have any problems, consult the Help pages on the IntelliSMS website
