>After almost 2 years, one of my applications is not working…

>So far, so good. BUT! Until now, it wasn’t necessary to dial numbers with more than 10 digits (US standard). Now they have to call 1-800 numbers (11 digits), and mi “dialer” doesn’t work! (Your call cannot be completed as dialed….) I verified the numbers, all valid.

I haven't used MSCOMM for dialing, but try putting in a comma or two after the "1", before the "800". A comma is a 2 second pause for AT commands.
