DTMF - mISDN - B100P - POTS

14 years 5 months ago #4104 by optix
Hi all,

I have a B100P card with mISDN driver installed on my Asterisk (1.4.24). Card is working properly, I can make inbound and outbound calls etc.

Problem is DTMF recognition (for IVR) from POTS lines. Whatever option I try, I can't get this thing to work. However DTMF works just fine when incoming calls are made from other ISDN or GSM network.

Current config:
/etc/mISDN.conf
<mISDNconf>
        <module poll="128" debug="0" timer="no">hfcmulti</module>
        <module debug="0" options="0">mISDN_dsp</module>
        <devnode user="asterisk" group="asterisk" mode="660">mISDN</devnode>
        <card type="hfcpci" dtmf="yes">
                <port mode="te" link="ptmp">1</port>
        </card>
</mISDNconf>
/etc/misdn-init.conf
...
card=1,hfcpci,dtmf
...
dtmfthreshold=100
I've tried with different threshold values (20,50,70,200,350,500), but no luck.. :(

Any help?
Thanks!

hello
Please try to add one line like the following:
relaxdtmf=yes
in misdn.conf file.

I did, but it stays the same. Still not getting dtmf from pots.

After I make changes, I restart asterisk and mISDN service (service mISDN restart, serivce asterisk restart). Hope I'm not missing out anything there?


Thanks
