>>>Dear all;
>>>
>>>After almost 2 years, one of my applications is not working…
>>>This particular one has a button which makes telephone calls using MSCOMM (AT commands)
>>>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 thought it could be the switchboard, but if you dial manually…it works fine, so, I have not idea what’s going on.
>>>Any help on this?
>>>Thank you,
>>
>>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.
>
>Thanks for your answer, I have tried (in advance) your suggestion, the same....
>In fact, I tried putting commas everywhere! Nothing changes. This is really weird.
Are you sure you're not on a PBX that requires you to dial "9" or something else first to get an outside line?
