   <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;">When a channel listens for DTMF in the core bridge, the outbound DTMF is not sent until we have received DTMF_END. For a long DTMF, this is a disaster. We send 4 seconds of DTMF to Asterisk, asterisk starts sending after and the call is interrupted for a total of 8 secs.

With this change, the DTMF_BEGIN frame is inspected and checked. If it matches a feature code, we wait for DTMF_END and activate the feature as before. If it doesn&#39;t match a feature, the frame is forwarded along with the DTMF_END without delay. By doing it this way, DTMF is not delayed.

I&#39;ve also changed two DTMF relay events to actually use the same duration as the incoming DTMF.

I have no experience of messing around with features.c and bridges, so please review this carefully. It is proven to work both in a 1.6.0 version and 1.4.

(I will remove the red code... Hard to miss)</pre>
