<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Using the AMI redirect action or ChannelRedirect application on a bridged call to transfer a channel can result in a stuck DTMF digit on the channel sending the digit.
Initial scenario that resulted in a stuck DTMF digit on a channel:
1) A is bridged with B (It doesn't matter who called whom)
2) B is sending a DTMF digit to A.
3) An AMI redirect action or the ChannelRedirect application redirects A to another channel or dialplan extension.
4) A will be stuck sending DTMF
Another scenario that could result in a stuck DTMF digit on a channel is the following:
1) A calls B
2) B is sending a DTMF digit to A
3) An AMI hangup action is done to B.
4) A will be stuck sending DTMF if it is setup to execute dialplan after the bridge exits. (Dial g option)

For DAHDI channels, the initial scenario would result in A hearing ringback even though C answered and C could not hear anything from A.</pre>
