Quick Dialler application for Gradwell VoIP Customers

Some time ago I produced an add-in to Outlook that enabled the calling of contacts directly from Outlook using Gradwell Call API. The app worked pretty well but I have recently redeveloped it into a standalone application and I think it works much better in this format. It still integrates with the Outlook contact database but the functionality is much easier to use in this format.

Introducing Quick Dial for Gradwell VoIP

So what does it do and how does it work?

Essentially the application allows you to initiate a call to your gradwell extension directly from your desktop without having to input the digits manually on your handset. Personally I find dialing the number manually quite a chore.

To support the quickest possible dialing it also:

  • Maintains a list of previously dialed numbers so you can quickly redial a previously dialed number.
  • Monitors your clipboard for a number so if you copy a number from another app it will be instantly available for you to call.
  • Queries the Outlook address book so that you can call any Outlook contact with a telephone number stored and automatically filters out e-mail only contacts.
  • When calling an Outlook contact will display the name and number of the contact being called on your handset.
  • Allows you to reverse the call order so that the call is only connected to you once the destination number has answered the call.

How to setup and use Quick Dial for Gradwell VoIP

Once you have downloaded and run the installer you will be prompted to enter your Gradwell authentication settings which you must do in order to use the application.

The settings are quite self explanatory and if you need more information on how to setup your Call API Authentication token then please read this document from the Gradwell website:


Once the settings have been saved you would be forgiven for thinking the app had closed down, but it is still running and it is accessible via the notification area:

I suggest that you change your notification area settings so that the Icon is always available, and then it will appear like this:

Now you can get started making calls. A single left click on the icon will bring up the main call window:

Once you place the call the status bar will show the status of the call and hopefully you will be quickly connected to the destination.

Calling Outlook Contacts

Right clicking on the application notification area icon will allow you to exit the app, change your settings on call an Outlook contact:

Choose “Call Outlook Contact” and as long as you have Outlook running and some contacts you will come to a dialog with a drop down, auto-complete enabled list from which you can quickly dial any Outlook contact.

Simply click on the hyper linked numbers available for your selected contact and the call will be placed. In addition, if your handset supports it, the contacts name will be displayed on the handset.

Let me know what you think of it, I’ve been find it very useful and saved me quite a bit of time/hassle.

Please note: I do not work for Gradwell and this application is entirely unsupported by them and I wrote it for my own use and I am just sharing.

Small outlook add-in to make Gradwell calls directly from Outlook

Having played around with the Gradwell API a little bit I decided to write a little addin for Outlook 2010 to make calls and send SMS messages directly without having to use my handset.

The add-in has two methods of initiating calls:

Right clicking on a contact in Outlook will bring up a list of all the numbers associated with that contact, which you can then select and call, as below:


Or you can choose “Communicate with Gradwell” from the add-ins ribbon bar:


Which will bring up the same dialog box but you will have to enter or paste a number in to the “Number to contact” textbox. The program will automatically strip any characters that the Gradwell API cannot accept – so you should just be able to press the call or SMS button and the action will take place.

Before you can make calls you have to setup your Gradwell call and or sms authentication tokens, which can be done from within your Gradwell control panel. Once you have your authentication tokens you can click the setup button within the add-in and you can enter the details as appropriate, your settings will be saved to your local registry:


Please note that when entering the SMS Originator number it must be a number associated with your account and entered in full international format, e.g. 441932565337.

More information on the Call and SMS APIs which this addin uses can be found on the Gradwell site:
