[asterisk-users] DTMF not reproduced towards ZAP T1 Port after connection when arrives as SIP

Yeah, it gets a bit confusing with all the scenario possible - Regardless,
you are right I should stay on 1.2 until 1.4 is ready for prime time, but
now that 1.6 is out, I'm sure I'm in for a long wait. I reposted my bug
again, since I think I may have listed it wrong - it's now
http://bugs.digium.com/view.php?id=12913 - Maybe now someone might notice :)

Thanks, Steve for your inputs

Bart


Asterisk has never been good at catching DTMF in rapid succession.  I
have read in many places that asterisk 1.4 had many changes to DTMF.

You contradict yourself below.  "The bad effect of inband mode was
> audio went one way after first press" and "One note: if I press say
'1111111' fast, it might hear '11', but not all digits sadly"

I suppose that you were using different methods.  Try pressing the
keys a little slower.

Personally, I would just go back to 1.2.X if you cannot get anyone to
acknowledge your issue.  What features do you need in 1.4 anyways?
Maybe if the DTMF bugs you opened get resolved then 1.4.X could be
revisited.

Thanks,
Steve T
