Hello dsandras,
welcome back to the Polycom Community.
As you have not specified which exact model display's what and which does not and specifically what version of software the working / non-working models are running this would be rather difficult to answer.
As long as the parameter is activated I am not aware of any reason, apart from a bug or an unsupported format, why we would not display this.
As a standard the following is turned off:
voIpProt.SIP.header.diversion.enable
I suggest you work with your known tier 2 contacts in EMEA so we can troubleshoot this.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
Polycom Global Services
