Hi Kanal,
It looks like when call transferred from Unity connection its taking a different route. Please check if the caller input is correct on the call handler it’s not getting looped with in the unity connection, getting forwarded to another VM.
Confirm that the forward timer in the phone system is synchronized with the Rings to wait For setting in Cisco Unity Connection
To confirm if caller is reaching the intended destinations we need to collect CCM logs, connection conversation manager or real time output for calls using Port status or RTMT.
