[Asterisk-Users] Problem with fax tone (CNG) from TxFax and busy detect

[Michael Welter]

I'm losing call files in /var/spool/asterisk/outgoing because * isn't 
able to detect the busy signal.  The call file looks like this:

Channel: Zap/g2/3036701917
MaxRetries: 1000
RetryTime: 60
WaitTime: 45
Application: TxFAX
Data: <filename>.tiff|caller
Using the "|caller" parameter, TxFax injects the fax tone (CNG) onto the 
line.  With the CNG tone, asterisk is unable to detect the busy tones.

If I were to remove "|caller" then the receiving station wouldn't 
receive the CNG tone and possibly not direct the call to the fax machine.

Is there a way for * to detect busy tones while ignoring (filtering) the 
fax tones?

Thanks,
