I wish this was Sangoma hardware esp. with hardware ec :)

My DTMF "bouncing" issues were indeed caused by echo but now that I've got
OSLEC running (thanks for patching that) calls are echo-free and crystal

The issue now is that my users dial their transfers (-say- #44) reasonably
fast and that often causes two successive DTMF digits to be detected as one

In order to reliably reach the extension the clerk cannot dial more than one
digit per second. That seems excessively slow. I suspect there must be a
knob somewhere to tune that (in libteletone)? Other causes to look for?
