[sv9100] Trunk to trunk transfer problem! Help!!

[pbxnewbie99]

I need configure a system as below
SL1000 -----> SV9100 ----> PSTN

SL1000
--
Trunk groups (14-05)
Group 2: trunk 5,6,7 (IP Trunks)
Group 3: trunk 8 (IP Trunk)

Incomming trunk types (22-02)
Trunk 5,6,7: DDI Mode Switching (all modes)
Trunk 8: Tie line (all modes)

F-Route
11-01: 8x (F-Route)
44-02: 8 (F-Route Table 2)
44-05-01: 3 (Trunk Group)

Interconnection (10-23)
IP Address: <SV9100 IP Address>
Dial Number: 8


SV9100

Trunk groups (14-05)
Group 1: trunk 1,2,3,4 (PSTN)
Group 2: trunk 5,6,7 (IP Trunks)
Group 3: trunk 8 (IP Trunk)

Incomming trunk types (22-02)
Trunk 1,2,3,4,5,6,7: DDI Mode Switching (all modes)
Trunk 8: Tie line (all modes)

F-Route
11-01: 8x (F-Route)
44-02: 8 (F-Route Table 2)
44-05-01: 1 (Trunk Group - PSTN)
44-05-02: 1 (delete 1st number)

Trunk
14-01-13: trunk to trunk transfer : checked (all trunks)
14-01-24: trunk to trunk outgoing caller id through mode: checked (all trunks)
--------------------------

Here is my problems (using SMDR report):

When i dialed 8xxxxxxxxxx from SL1000, it sent my dialed number through trunk 8 (tie line) - OK
But SV9100 received my number through trunk 5 (DDI) instead of trunk 8 (tie line) - not OK

It always received my number through trunk 5. If i change trunk 5 into tie line, i can dial external number but other settings using DDI (trunk 6,7) will not work

How to configure SV9100 to receive my number through trunk 8 (tie line) only?

The above settings only work with tie line trunk type. How to setup the similar configuration using DDI trunk type?

Thanks
