A new chapter in
Asterisk versions 1.4 and lower tend to do weird things with DTMF unless
certain precautions are taken. The best thing you could do at this point
is try to find an ITSP that uses Asterisk 1.6 and up or one that doesn't
use Asterisk.

Josh,
We are *NOT* using Asterisk. See the
Ah, Josh is implying (correctly) that a lot of ITSP's use Asterisk. You can
see the UA version in your failed transactions.
Get another ITSP. There are a lot of them out there that seem to work well.

Ah! Gotcha. Sorry
Using PRI and mediant 1000, so no ITSP
I do have a Trixbox system in production at a small office and they
sometimes have DTMF troubles, hence my comment.

What would be really interesting trace wise is the SDP headers showing the

I am somewhat doubtful that the DTMF setting are at issue here. I say that
because whether through an Ingate, PRI or sipxbridge I have never seen this.
All the above does is indicate someone pressed a key a bunch of times.
Is a siptrace available?

OK, it looks like my understanding was way off base.
On the advice of Dave D., Eric V. and Dave W., I’ve tried:
- Locking the phones into G.711
- Increasing the DTMF On/Off times from 50 to 150 (tested at 25ms
increments)
