Configuring Asterisk to support Data calls

Hi All…

Plz can anyone help me on how to configure Asterisk to support Data calls(FAX.). Is there any such setting or what is the proper way to configure this…

Waiting for Help…


what kind of FAX, from ip to pstn or between ip ATA? if you need fax from ip to pstn, you need some cards or FXO ATAs.

Hi All

My configuration is as follows

ISDN setup message contains the BC as to send the fax message.which then goes to the gateway and gatway convert the SDP as clearmode and send to the asterisk.But asterisk when send it to the gateway it does not change the SDP as clear mode which cause the it forward the message as audio call and forward to the 2nd user .

So to support this i have change something in config file .Please help on the same.
