A102 sangoma dual Pri trunking pri_cpe working but pri_net not working

Hi all
My scenerio is |Nortel|-----PRI---------|Trixbox|------PRI-----|PSTN|
Trixbox have A102 Sangoma Pri Card.

I want call to each other and nortel dial to PSTN and vice versa. My problem is bellow.

|Nortel|-------------|Trixbox| (working fine)
|Nortel|-------------|PSTN| (working fine)
|Trixbox|-----------|PSTN| (working fine)
|Trixbox|-----------|Nortel ( not working )
|PSTN|-------------|Trixbox| (working fine)
|PSTN|-------------|Nortel| ( not working )

My configuration is

zapata-auto.conf
-----------------------
;Sangoma A102 port 1 [slot:2 bus:6 span:1]
switchtype=national
context=from-zaptel
group=1
signalling=pri_cpe

;Sangoma A102 port 2 [slot:2 bus:6 span:2]
switchtype=national
context=from-internal
group=2
signalling=pri_net
channel =>32-46,48-62

---------------------------------------

I make two trunk and also change the name Zap/1 and ZAP/2

outbound Route define on each trunk 9|. for Zap/1 and 8|. for ZAP/2

as above diagram when we call through Trixbox 8|. to nortel its not working it shows bellow error
