I have an external hot desk user but when the call forwards to that external number it is showing the Default CPN instead of the originating caller's ID.
I have tried ever setting I think might have an impact in the SIP Peer Profile, the COS for the extensions, as well as the COS for the SIP Trunks. I had this workin on the AX controller but can't remember where the magic spot was.
Of course, I have search high and low on these forums but nothing that fits this situation.
