dtmf is working in 1.4.11 but not on 1.4.17

I am happy to upload some failed Snom SIP INFO output.
I'll post soon...

I just tested audible DTMF on my Nortel SL1 and Nortel Norstar and Nortel
BCM and this does work. And I'm sure this was supported in Asterisk at one
time or another.
We suppress DTMF when we do automon or similar native Asterisk feature
code and I think it is the interdigit timers between DTMF digits which
tells/told Asterisk to suppress DTMF playback when we invoke a feature.

For what its worth I think DTMF suppression is a minor issue as and it
isn't service affecting. I just noticed the audio is now suppressed and
thought it was a bit weird.
