Help blind veterans

I currently am working for a non-profit organization and we are trying to help blind veterans. We are looking for an application that can be used in conjunction with spark chat and JAWS to allow content of the chat (as in phone numbers) to be pulled out of the chat automatically and sent to an API to be dialed without that veteran having to try to dial the number manually. Currently in my research no such thing exists at this time. Is there anyone in this forum that would have an idea on how this could be done?
