neither of both - I'm using a plain cellphone connected via bluetooth
(latest chan_cellphone-patch). maybe that's the root of my troubles...?

anyhow, after further testing I tend to beliebe that it's not the _duration_
of actually pressing the key, but rather that asterisk requires a minimum
period of silence (~0.5sec) _between_ the key-presses to recognizes
everything correctly.

is there anything I can tweak according chan_cellphone?

thx!
