Here i send you a extract of the modem manual. I hope you'll find out which was the problem :?
2.3 Using SVD function
The modem can provide SVD features optionally that allow
Simultaneous Voice and Data transmit through one single
telephone line. This high technology feature enables users to do
voice conversation with remote end while sharing data or
playing interactive games.
To operate in SVD mode, both the local modem and remote
must be enabled to support SVD mode. A handset or
microphone/speaker must be attached to the modem
connectors in addition to the phone line. Please reference the
following example to enable this function.
Example 1:
Local Modem Remote Modem Comments
DTE DCE DTE DCE
AT&F OK AT&F OK Reset modem
AT#VLS=0
(or
AT#VLS=6)
OK AT#VLS=0

(or speakerphone) for
voice conversation

Chapter 4:
AT Command Set
4.1 Executing Commands
Your modem is in Command Mode upon power-on and is
ready to receive and execute <93>AT<94> commands. The modem
remains in Command Mode until it makes a connection with a
remote modem. Commands may be sent to the modem from
an attached terminal or a PC running a communication
program.
This modem is designed to operate at common DTE speeds
ranging from 115.2 Kbps to 300 bps. All commands and data
must be issued to the modem using one of the valid DTE
speeds.
4.2 AT Commands & Formats
All commands must begin with the AT prefix, followed by the
command letter and end with the ENTER key. All default
settings are printed in bold text. Spaces are allowed in the
command string to increase command line readability but are
ignored by the modem during command execution. All
commands may be typed in either upper or lower case, but you
cannot use both in one command. A command issued without
any parameters is considered as specifying the same
command with a parameter of <93>0<94>.
Example: ATL[ENTER]
This command causes your modem to lower its speaker
volume.
4.3 AT Commands
All default settings are printed in bold text:
