<div>I'd be interested to understand where you read about the 'sequence numbers' issue. </div>
<div>This sounds like it might relate to the problem I am experiencing.</div>
<div> </div>
<div>It's either that, or the DTMF is coming inband over the IAX channel...</div>

http://bugs.digium.com/view.php?id=4631</a><br>> Does this bear any relation?<br><br>I'm not sure. Incoming DTMF using IAX2 from the PSTN via my provider to my<br>box seems to work fine. When my box tries to send DTMF, it appears that
<br>the first digit of the string is translated by the provider into DTMF tones<br>over the PSTN, but then subsequent digits in the same string, although sent<br>by IAX2 from my box, are not translated by the provider.<br>
<br>I remember reading something some time ago about DTMF getting lost due to<br>sequence number problems, but I can't remember whether that was SIP or IAX.<br><br>I'm hoping to avoid having to delve into the code myself, due to lack of
<br>time, and I'm not even sure whether the problem is my end or the provider's.<br><br>Cheers<br>Tony<br><br>> Mark<br>> On 7/12/05, Tony Mountifield <<a href="mailto:tony@softins.clara.co.uk">tony@softins.clara.co.uk
