error 526no dialing tone on SMS test



I connected an analog modem to a pbx where i have to dial 997 before i have a dial tone.

If i test the sms settings (phone number to dial service provider starts with 997.....) I get the error 526 [there is no dial tone]. How can i get this solved?

The windows settings are NOT set to wait for a dial tone...via hyperterminal the modem works OK.

    Dear Jens,

    The SMS module is designed to dial only when there is a dial tone. I will check with the development to see if there is a possible workaround for this (in terms of developping a new version)
