Hi, I just trying configure Iaxmodem-Hylafax-Asterisk, I can receive fax correctly, but when I try to send fax looks like as the iaxmodem is not sending a typical fax sound, you can ear only a beep each 5 sec. I have tried with alaw and ulaw potocol, but no lucky.
Thanks in advance.
Sending a fax is supposed to send that beep each 5 seconds. That's called CNG. It is the receiver that initiates with fax tones.
