[Freeswitch-users] Strange DTMF Tones On Inbound Calls

OK, I’ve added the BDA’s to the ISDN dialplan and removed my binding for parking calls (no-one uses that apart from me – I find it very useful!).

Let’s see what happens…

Maybe bind_digit_action would capture these for you. You could try binding something simple, like a log function:

<action application="bind_digit_action" data="rogue_dtmf,~\w+,exec:log,INFO Rogue digit(s): ${last_matching_digits}"/>
<action application="digit_action_set_realm" data="rogue_dtmf"/>

You'll need to experiment to make sure that regex works. If not you could possibly do each digit explicity, like this:
<action application="bind_digit_action" data="rogue_dtmf,A,exec:log,INFO Rogue digit: DTMF 'A' received"/>
<action application="bind_digit_action" data="rogue_dtmf,B,exec:log,INFO Rogue digit: DTMF 'B' received"/>
<action application="bind_digit_action" data="rogue_dtmf,C,exec:log,INFO Rogue digit: DTMF 'C' received"/>
<action application="bind_digit_action" data="rogue_dtmf,D,exec:log,INFO Rogue digit: DTMF 'D' received"/>

I don't honestly know if this will work, but I'd like to see what happens in your case. FYI, you can read up on bind_digit_action (AKA 'bda') here:

Interesting, how would I do this?  Can’t use “bind_meta_app” since that only works with numbers…  The tones appear from the caller not the callee (leg A).

If all you wish is to purge the tones from your stream you can simply capture them in the dialplan, no need to mess with the source...

Best,

I appreciate your honesty, Gabe.  But seriously, is that the reason no-one else is responding or is it because no-one has any ideas?

Unfortunately, I don’t (and can’t) control what appears on my signature as it’s added by our e-mail gateway not my e-mail client (if it can’t see a signature on the e-mail it will add it).

I'll be honest. I haven't followed the thread because of the loud, in-your-face advertisement in the email footer. Nobody is going to make you remove it, but they might respond to more of your emails if you show them that you respect the list by not cluttering it with noise.

Just my 2 cents.  And of course good luck on the issue.
