If you own that website, you could turn your webpage into an ASP webpage that can run code.  The code would store the phone number directly into a table in Access -- or SQL Server, which is more suitable for web usage.  If your webpage is on the Internet, your table likely needs to be hosted on the Internet also, hence SQL Server is more suitable.  The code would involve running a simple append query such as: INSERT INTO MyPhoneNums (phonenum) SELECT phonenum_fromweb .  The coding language (one of several) for ASP webpages is VBScript, which is VBA's little brother.  This is a fairly simple problem to solve if you are able to put your database online and use the above method.

Yeah, I like Kevin's solution. Your Access database could run on a timer and check that table every couple of seconds and pop up the customer's record on your screen. Much more elegant than trying to watch your web browser from Access.

Or better yet - just move ALL of your data to SQL Server Online and then you could have a full page of your customer's info pop up instead of just their phone number.

How is your web browser opening now? What's opening it? Your phone software?

Kevin and Richard.  Thank you. I did this and More.  
1. I created an SQL database using Winhost
2. Made an ODBC Connection to an ASP page that has a Timer.
3. RingCentral Opens an ASP page that delivers the Phone Number Ringing to the ASP page.
4. Using a local Database ("Monitor.accdb) i read the remote Database every 3 seconds. Look up the Customer and Display it
5. Double clicking the Customer it opens up the file

Great Collaboration Guys. Thanks again

Awesome. Very impressive!
