Getting busy tone when call forwarding is configured on a 8841 phone. call forwarding is working on all other phones in the cluster.I have configred proper CF CSS and also made sure the forwarded extension is working. while searching on the support forum found a bug CSCuc98295, but couldnt find any workaround for this. my CUCM version is 11.5.1
Someone please help to find the root cause of this issue, i have attached traces from CUCM.
