hi,
i am trying to detect fax tone on outgoing calls. here is my javascript code
+++++++++++++++++++++++
session1 = new Session("{ignore_early_media=false}sofia/gateway/flowroute/"+argv[0]+"");
session1.execute("tone_detect", "fax 1100 r +30000 set 'fax_tone_detected=true' 1"); msleep(argv[1]); session1.hangup();

i checked pcap file and using wireshark , i can hear sone tone on rtp audio playback.
but freeswitch cant detect that..
is there any other solution to find out specific tone like fax??
thanks in advance
Was this the one we talked about yesterday where your fax machine was really spitting out a tone around 2096Hz?
Of course it spits out around 2096Hz. An answering FAX machine sends a burst of 2100Hz tone, and then V.21 preamble. Its the calling machine which sends 1100Hz. Steve
