How to enable DTMF tone?

Hi
i have a problem because i can not press any number if the ivr on other line is active.
For example when the voice tell me: press 1 for, press 2 for, press 3 for, etc… if i press don’t go.

What i have to set up on my freepbx?

If i add a new extension on “dtmf signaling” in my freepbx i have only 3 choice:

  • rfc4733
  • sip info (application dtmf/relay)
  • in band audio (not raccomanded)

On x-lite or on my ip phone i saw i have RCF2833, maybe this is the problem?
How i can make for use DTMF?
Thank you

This is not a FreePBX forum and Asterisk has not built-in IVR capability; that is implemented by FreePBX dialplan. Peer support for FreePBX is available at community.freepbx.org/

RFC 4733 is backwards compatible with RFC 2833 (and the latter is often used loosely to mean the former).

hi
ok thank you
i’m sorry, i thinked is correct to write there :smile:
Now i try to ask in the freepbx forum
Thank you

Use dtmf=auto
in sip.conf file or which sip id you are using

If dtmf=auto does not work use

dtmf=rfc2833
