Hello Friends!
I was wondering if someone could advise me how to setup CPN substitution.
I used an extension outside of a certain range and now I want to setup that extension with the
same CPN substitution as that range.
I added one under DID Ranges for CPN substitution form under Trunks\SIP but it didn't work.
Did I put it in the wrong place or is there another place I need to update as well.
Thanks!
