(Zap? SIP?) Looks like a DTMF detection problem. If ZAP, you better use longer tone. You can try relaxeddtmf in zapata.conf, but people generally recommend against it. The card you use also matters. Heavy echo could also interfere with DTMF. If SIP, the symptom you described would happen only to inband DTMF. Try not to use inband if you can help it.
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!
