[Freeswitch-users] fax tone detection failed

[romon.zaman]

hello MC,
you are right..
before this published here, you help me to get a solution.

actually, my fax machine was not sending standard fax tone.  but it worked with actual tone frequency.

so, if someone ever face this problem, recommendation is to get pcap file and extract audio file from RTP with wireshark and analyze audio with audicity to get exact frequency of tone.

and when u use tone_detect with exact tone frequency, it will work perfectly.


thanks for  your help

    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?
