on D130 DTMF does not pass everything

Hello,

from a third-party PABX, I access Asterisk messaging.
no problem for the number of the voice mailbox and the password and I go into my box.

I'm trying to do 1 to see my messages ... but it does not take it and continues the different menu choices

Sometimes it works very well but it's a bit random

What could I play on?

voici mon dahdi_channel

; Span 1: D115/0/1 "D115 (E1/T1) Card 0 Span 1"
group=0,11
context=from-t2
switchtype = euroisdn
signalling = pri_cpe
channel => 1-15,17-31
overlapdial=yes
relaxdtmf=yes
context = default
group = 63



Thanks
