Please forgive me because I was wrong.
After downgrading zaptel DMTF works much better, but for some reason
numbers "1" & "2" are not send through DTMF. Every other key
(including "*" & "#") work like a charm.
DTMF works nicely in the LAN side (i. e. voicemail login) , but if I
try to reach our voicemail from the outside I see any key pressed
except "1" & "2".


Telephone is Grandstream GXP-2000, but I think I should blame my * . I
know we are having this problem when dialing through Zap channels
(Digium TE120P card)

Any hint?
