X100P/X101P No cuelga linea analogica

[apoloco]

Hola,
Tengo un problema con con el colgado de linea , tengo un modem sweex con el chip ambient . Me lo reconoce perfectamente:

Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
Subsystem: Intel Corporation Digium X100P/X101P analogue PSTN FXO interface

Y recibe llamadas ... pero el problema es que cuando asterisk lanza un hangup no cuelga la linea .

-- Starting simple switch on 'Zap/1-1'
-- Executing Hangup("Zap/1-1", "") in new stack
== Spawn extension (from-pstn, s, 1) exited non-zero on 'Zap/1-1'
-- Hungup 'Zap/1-1'
-- Starting simple switch on 'Zap/1-1'
-- Executing Hangup("Zap/1-1", "") in new stack
== Spawn extension (from-pstn, s, 1) exited non-zero on 'Zap/1-1'
-- Hungup 'Zap/1-1'

mi configuracion zaptel es:
fxsks=1
loadzone = es
defaultzone = es
y zapata.conf :
[channels]
language=es
context=from-pstn
signalling=fxs_ks
rxwink=300 ; Atlas seems to use long (250ms) winks
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=no
echotraining=800
rxgain=0.0
txgain=0.0
group=0
callgroup=1
pickupgroup=1
immediate=no


Gracias de antemano.
