Transfer causes DTMF signals

[tommy_fc]

When clicking on transfer in the user interface, there is a sound of DTMF signals in the users conversation. I assume this must be matched in the dialplan? What signales does it send? And how can I match this in my dialplan?

I am using asterisk 1.6.2.2, a pretty stripped down version, so no trixbox or other GUI.

It is an asterisk bug. Update to trunk and it will work. Best regards,

[tommy_fc]

Could you please refer to the specific bug?

Using trunk is not an option in production, but upgrading to 1.6.2.3 might be, if the issue is fixed.

[nicolas]

No, I cannot point you to the specific bug. I have other users with that problem, and it was fixed when updating to trunk. You are free to search it for yourself at http://issues.asterisk.org

Just for starters: https://issues.asterisk.org/view.php?id=16816

Hi,
I have the Problem too. But it wasn't fixed after updating. Now I use asterisk 1.6.2.11 with FreePBX.

Attended transfer (atxfer) is run on asterisk too. Someone can help me?

[nicolas]

I am sorry, but it is not a fop2 problem , but an asterisk bug. If the manager atxfer feature causes dtmf slips and no transfer to occur then you can report the bug to issues.asterisk.org.

I tried 1.6.2.3-rc2, 1.6.2.5, 1.6.2.9, 1.6.2.11 and trunk and no Version works. Could you tell me a working version or which asterisk configuration files could change?

[AlexRS]

Hi! I have the same problem with asterisk 13.8
When I call from panel to extension and try to transfer via 'Dial' window, I hear DTMF. But if I try to transfer via 'transfer' button, all works fine.

The issue happens only if call originated from me and I try to transfer by panel. If I transfer with phone (yealink) transfer works.
Is it asterisk bug?

PS. Sorry for bad English(

[AlexRS]

UPD. Commands in log looks the same. It means asterisk issue.

-> Action: Atxfer
