We are in the process of changing our extensions to a new extension layout. When we make the changes on our DN on the phone and Lines it doesn't seem to update the auto attendant with the new DN. When we use the DID number it works perfectly, but when someone dials our main number and then tries to dial the nex extension 7041 instead of the old one 4201 they get the extension not found response.
One thing is when we use the new extensions we can still dial directly internally but not externally.
We are using Cisco Unified Communications Manager (Cisco Call Manager 4.1 and Unity 4)
