Hello,
I'm wondering if there was a resolution to this? I'm having the same issue with one of my sets. I run vMCD and all of my phones are programmed off this one controller. The particular extension that gives me the same error produces this when trying to hot desk in with that extension on multiple phones. I've reset the pin and deleted the ext. multiple times and have built is using multigroup and none multigroup. COS is the same as all of my other sets. I've tried coping working hot desk extensions. All with no luck. My log shows me the following 3 logs associated with my issue.
LoginManager::sHandleLogin() -> on dn(1234),mdn(1234) entry is marked as RegDN, reject the login, send mobilityResp (13) msg
Hot Desk : redirect or update failed for *1190
Hot Desk : Login failed at *1190 - Redirect or update issue
thanks,
