[Asterisk-Users]Hangup with error

[asterisk183]

I used quadBri Junghanns card and I config
zaptel.conf:
ZAPTEL.CONF
loadzone=it
defaultzone=it
span=1,1,3,ccs,ami
span=2,2,3,ccs,ami
span=3,0,3,ccs,ami
span=4,0,3,ccs,ami

bchan=1,2
dchan=3
bchan=4,5
dchan=6
bchan=7,8
dchan=9
bchan=10,11
dchan=12

point-to-multipoint mode)

point-to-point mode)
;signalling = bri_cpe

;signalling = bri_net

pridialplan = local
prilocaldialplan = local
nationalprefix = 0

echocancel = yes

group = 1
channel => 1-2

group = 2
channel => 4-5

group = 3
channel => 7-8

group = 4
channel => 10-11

But when I hangup the channel, Asterisk show this
message:
