Trunk to Trunk transfer

[CommoGuy101]

Morning everyone,
I have an issue with trunk to trunk transfer...I believe

I have a local PRI on my Nortel CS1000E with a block of 100 DID numbers
Recently, I have set up a TIE trunk between the Nortel and Cisco.
I have taken a DID number and then did a CDP of that number to the Cisco system.
If I dial the 5 digit extension number from a Nortel phone the call follows the correct RLI and route to Cisco without any issue.
However, if I dial the 10 digit number externally, the call is not flowing to the RLI and following the route to Cisco.
The call is diverted to the 2250 console at the reception desk on the Nortel system.
They are able to transfer me to the extension that is on the Cisco phone.
Seems that I may be missing something that allows trunk to trunk transfer from the Local PRI to the Tie trunk connected to the Cisco system.
Any thoughts?


Thank you all,

Check the customer data block and make sure you have EXTT and TRNX set to yes. These are the 2 prompts that control external trunk to trunk transfers.

I checked the CDB and those were already set to yes

DITI YES
TRNX YES
EXTT YES
FTOP FRES


When I check the ESN I have noticed that all were set to 0
When I look at my other sites those are set 0-,1-1,2-2 and so forth

NCOS 0 - 0
NCOS 1 - 0
NCOS 2 - 0
NCOS 3 - 0
NCOS 4 - 0
NCOS 5 - 0
NCOS 6 - 0
NCOS 7 - 0
NCOS 8 - 0
NCOS 9 - 0

Could the change make a difference?
As far as I can tell all of the route members are NCOS 0 and all phone sets are NCOS 0

Yes I would set them all to match this may not fix the issue but is much cleaner. Also you may want to look at the FRL on the routes as the NCOS needs to match or exceed the FRL on the route.

FRL is set to 0 on the routes
Changed the settings for the NCOS
Still getting the same results.

Extensions on Nortel can call extensions on the CISCO using the CDP routing.
Only fails when a call comes in on the local PRI then trying to route via CDP to the CISCO.

All has been resolved.
Ended up being an issue with PNI.
They were a mismatch.
The ISDN (local PRI) was set to 00000 for the PNI
The TIE to Cisco was set to 00001
Changed them to 00000 so they would match and "BOOM" all is working properly.

Thank you all,
