Cannot send DTMF 0

Added by Guilherme Bizzani over 1 year ago

Hello all, I'm having this trouble since the beggining.
All DTMF's work fine, but DTMF 0 doesn't.
I've already tried to debug some parts of the code, but by what I see everything is equal independent the DTMF code that is being passed.
I've copied the SIP Debug in Asterisk's console,

Hi,

May we know from what part your having issue in dtmf?

1. Sending DTMF while in outbound?
2. Sending DTMF while in inbound?

Please provide us steps to replicate the issue and sample number if possible.

Thanks

It's on outbound calls.

The carrier that I'm using with all campaigns is an IAX to another asterisk server, so I decide wich route I'm going to use in this other server, but the console's log that I posted before is from the GoAutoDial's asterisk console.
In the other server I receice nothing when the DTMF pressed is 0, but I receive it normally when it is any other DTMF.

I've already tryied all the dtmfmode options in the IAX configuration, I even try to make the Carrier use SIP protocol, but the DTMF keeps failing at 0.

I don't have any public number to test DTMF, but I made this context to store whatever the user type and say it back to him:

[dtmf-test]
exten => 5080,1,NoOp(DTMF TEST)
same => n,Read(digits,,9)
same => n,Wait(1)
same => n,NoOp(User typed ${digits})
same => n,SayDigits(${digits})

Hi,

For troubleshooting please try to configure your VOIP directly in your GOautodial Server and test DTMF.

Thanks

Hi all.

We faced the same problem with DTMF during established onnection.
Dialing of all digits is works well except digit "0".
Digit "0" doesn't send to carrier.
There isn't problem on VoIP operator's side.
We tryed use rfc2833 and inband. With no luck.

Could you explain cause of the problem?

This is log from asterisk for digits 0 and 1

I've resolved this problem.

I changed code in file /usr/local/bin/listener.pl

if ($key) if ($key || $key == 0)

replaced by

Good to know.

Thanks for sharing.

This has been fixed 5 months ago. You can download the updated listener.pl from our Github repo: https://github.com/goautodial/appkonference.

In the last commit bea8e2e702ce35dd295a03725e8de9df983a664f such changes:
- if ($key =~ /^[0-9]+$/) {
+ # https://goautodial.org/issues/7303
+ # if ($key =~ /^[0-9]+$/ | "#" | "*") {
+ if ($key) {

and "if ($key)" return false when $key=0

Could you explain where I mistake?

Your solution is also good. Ours is just more specific - limiting the DTMF to keys in the dial/numeric pad only.
