OK, i think we have a little misunderstanding here.
You have 3 companies.
1 = 1888-111-1111
2 = 1888-222-2222
3 = 1888-333-3333
When someone calls 1 and it’s being forwarded to a cellphone you want the CID to show on the cellphone as 1888-111-1111, and so on with the rest of the companies.
Is it this what you want?
