I have successfully added the Region column to the Order Management table (item 1).
kindly proceed with releasing patch 3.7.0.1384.
Note: This release requires refreshing the FN server.

Slide 4 : In the solution that deletes an existing trail reserved for a specific subscriber, the flow first check whether the subscriber exists in FN , If the subscriber does not exist, the error message "Subscriber does not exist" is displayed, If the subscriber is valid the flow retrieve the required data from FN to generate the request sent to the iLink API based on the subscriber type.
patch 3.7.0.1405

as received from ILiNK team , we need to put below values in existing API when doing Switching Voice Release Resources for NGN or IMS with trigger process

DEVICE_ID = DUMMY this indicates iLink to skip the access node commands.
ORDER_NO is mandatory input in any request to iLink hence you may generate any random number and send it for NEP enhancement related scenarios.
proposed random value: FixedlineNumber + TimeStamp for example:
4500120131032026132259

this is applicable for below scenarios - to be mapped with Slides nb shared by customer
1. Delete Copper voice only either from NGN or IMS
2. Delete GPON voice only either from NGN or IMS
3. Create copper voice only on NGN or IMS
4. Create GPON voice only on NGN or IMS

In addition , we need to create a seperate report in FN GUI to display the requests done by the users for audit purpose - shamim and Ayed to agree on possible fields to be added in solution document and take approval on it.
