Change 600 DID Line Group number at one time in ICR 1

[eaglepromopro]

Hi,
I need to change the Line Group ID number from 12 to0 for over 600 DID numbers. There is a lot of custom routing so I would rather not delete all the DID number and recreat them using MSN tool. IS there a way to change all of a them at one time like I would on a PRI channel?

Thank you

Save an offline config in case you screw up and need to push the previous config into the system.
Reconnect to the IPO and export the config as a .csv
Open the Configuration.cfg file and trim down to the section from (including) IncallRoute_Info_Start through (including) IncallRoute_Info_End
Change the line group numbers as needed
Save as .csv
Open in Notepad and remove the extra commas after IncallRoute_Info_Start and after IncallRoute_Info_End, save the file
Import the modified confguration.csv file into the IPO and, after checking that everything is correct
Merge
