Hello EricT,
welcome to the Polycom Community.
I only had a brief look but it seems that we only partly support RFC 3326 Call completed elsewhere.
It seems this only works on shared lines and uses the call.advancedMissedCalls.reasonCodes Parameter to define what reason codes are used.
I suggest you work with a Polycom Reseller in regards of the full support and quote VOIP-26549.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
