Asterisk 1.6 with dahdi-linux-complete-2.0.0+2.0.0 ERRORS

Hello

I recently installed Asterisk 1.6 with dahdi-linux-complete-2.0.0+2.0.0.
Into mashine I have a Wildcard TE405P (2nd Gen).
I made a scheme to test the asterisk like this:

phone -> audiocodes mp118 -> peer2peer -> patton SN2400 -> isdn(e1) -> asterisk

My config files:

/etc/dahdi/system.conf
span=1,1,0,ccs,hdb3,crc4
loadzone = uk
defaultzone=uk
bchan=1-15
dchan=16
bchan=17-31

/etc/asterisk/chan_dahdi.conf
[trunkgroups]

[channels]
callwaiting=yes
usecallingpres=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=no
echocancelwhenbridged=no
;rxgain=2.0
;txgain=3.0
busydetect=yes
busycount=6
;faxdetect=both
;faxdetect=incoming
;faxdetect=outgoing
;faxdetect=no
;overlapdial=yes

group = 1

context=from_pbx
language=en
switchtype=euroisdn
;switchtype=qsig
pridialplan=unknown
prilocaldialplan=unknown
;priexclusive = yes
resetinterval = 3600
signalling=pri_net
channel => 1-15
channel => 17-31

/etc/asterisk/extensions.conf
[from_pbx]
include => parkedcalls
#include contexts/test.ctx

/etc/asterisk/contexts/test.ctx
exten => 807505,1,Answer
exten => 807505,2,Wait(2)
exten => 807505,3,Playback(…/moh/fpm-sunshine)
exten => 807505,4,SoftHangup(${CHANNEL})

Everything look good, exept 3 things.
1.When i restart the isdn link somethimes i get the next error:
[Nov 26 18:43:43] ERROR[15377]: chan_dahdi.c:10112 dahdi_pri_error: !! Got a UA, but i’m in state 6

2.On everycall i make from the phone, through patton to the asterisk, i get:
[Nov 26 18:46:19] ERROR[15377]: chan_dahdi.c:10112 dahdi_pri_error: !! Unexpected Channel selection 3

,but the call is working

3.When i reload chan_dahdi.conf from asterisk console, i get :
Ignoring switchtype and Ignoring signalling

Please help!
