Tie Trunk to CO Trunks not working

[imperium1]

Hello, my name is Chris and i am one of the Panasonic Installers for my company.
My customer has 2 locations within the same town, a north location and one on the west side.
The North-side is a Panasonic TDE200 running version 8.0101.
The South-side is a Panasonic TDE100 running Verison 8.0101.
We've setup the the IP Gateway so we use extension dialing to communicate between locations. (No PBX access Codes)
The North-side is using 1xx extensions and 3xx extensions, while the West side uses 2xx Extensions and 4xx Extensions.
We have 8 IP trunks connecting the buildings across a VPN tunnel.
We are able to call from one building to the other by dialing extension numbers.

The issue is that there is a 23 Channel PRI service at the West Side, but only a 7 line Analog Rotary at the north location.
What we would like to do is have the north side be able to dial out on the west side's PRI.
at both locations, the Telco trunks are Trunk Group 01 and the IP Trunks are Trunk Group 7.
both are in Class of service 1 with both forward to CO and transfer to CO enabled.

The manual says i have to dial the trunk group access code "8" and then the group number of the IP Trunks "07" then dial 9 to get idle line. Whenever i try this or dial the TIE line access number "7" and dial 9 for idle line, i instantly get re-order tones.
If i forward an extension at the west side to an outside number, and call that extension from the north side, calls route to the forwarded number out on the west side's PRI. I just can't find out where the issue is preventing The North Side from Accessing the West side PRI.

Any suggestions?

Class of service of the tie trunk group should be 1 to allow dialling.

routing of numbers to the lines have to be in incoming and outgoing dial table in the card settings and in the system table

if you use 7 by default this just picks up the tie lines, you would need to dial 9 or 80x plus number to access the trunks on other system.

the number plan should allow 80x plus number of digits after that, can be more than needed but not less

incoming digits on the ipgw card will have to allow 8 or 9 in as well.

so the number plans have to be different on each system or 7 plus the digits you want on the other system.

you could use quick dial codes to dial longer digits i.e 81 dials 7801 for trunk group 1 on other system
