Description:Hi guys,

I'm trying to play dtmf digits to a channel, but it's not working. To test its is very simple, I made:

0. Enable full in logger.conf (exec tail -f /var/log/asterisk/full)
1. Register two sip phones
2. Call from one to another
3. Get some channel (show channels)
4. Login manager (telnet localhost 5038)
5. Send event:
Action: PlayDTMF
Channel: SIP/556-0859cdd8
Digit: 1

Thanks guys.. I hope that additional information help to found root cause.

Ps. I don't know the correct category and I'm receving an error when I try to select .I did not set the category correctly.

The log messages you are pointing out are for DTMF received *from* a channel, not sent to one. The manager action you are executing is sending the DTMF digit '1' to channel SIP/556-0859cdd8. What is the device in question? Is it muting the DTMF? Can you attach an rtp debug if using RFC2833 to see if the digit is getting sent?

Hi file,

I tried to sent DTMF to both channels trying to figure out some "my own" mistake, but it don't see DTMF an anyone of them. I will try to explain what I'm expecting:

I made a call from SIP/115 to SIP/556 and I try to send "DTMF digit 1" to SIP/115.

Yes, I can sent to you an rtp debug. Do you need an rtp debug from tcpdump or can be from asterisk cli command (rtp debug). From tcpdump can you have show me the command that you need?

I'm using RFC2833 (DTMFmode: rfc2833) in both peers (SIP/115 and SIP/556)

Bye

I think you misunderstand the action. It does not send DTMF as though it came from the device, so you will never see the log messages you pointed out. It sends DTMF to the device. Asterisk will never see the DTMF.

Closing this out because it is not a bug.
