Hi all, thanks for replying.

I didn't touch dtmf settings since I realised that the problem was with my phone. Sure, it's strange, but it seems to be working on other phones just well. My phone is Siemens Gigaset SL100, connected through Asterisk (via cisco ATA), but I also tried with direct connection to pots... I haven't had time to look into it more deeply, I just left it the way it is.
I'll try with
card=1,0x4, dtmf

Thanks!

Hi,

i think, the problem is in the channel-driver from asterisk.
please try in the configurationfile /etc/asterisk/misdn.conf

following in the section default:

[default]
senddtmf=yes ; if set this no, asterisk will not progress inband dtmf signals.
astdtmf=yes ; if this sets to yes, asterisk will making the decision about dtmf.

regards

Patrick
