>>>Yes. Until your modem sees and negotiates with another modem, it appears to be staying in command mode so you should be able send digits until the modem reaches it's dialing timeout. Having fun yet?

I think one of the reason why it doesn't work, as per the silence I am waiting for before sending the next command is because the modem is defaulting to a 5 second silence in order to execute the next command after the @ command. As my voice mail only waits for about 2 to 3 seconds before saying we haven't heard your recording, I never reaches that delay.

The command is going like this:

oPhone.Phone.Output='ATDT1234567@1;'+CHR(13)

So, what happens, is that it dials and wait for a 5 seconds silence before sending the 1 character. But, we only have 2 to 3 seconds to record before the voice mail validation message kicks in.

How can we change the silence wait for duration?
