I have setup Webex Hybrid call connector a few months ago and then it was working fine.
The Expressway-C & E are now upgraded to x12.5.4 and the Call connector version is: 8.10-1.0.7252.
But now all calls from Webex Teams to UCM registered phones are failing. Seems the call originates in the Default Zone instead of the created Webex zone. The search history shows this error: Not accepting pre-loaded route headers
