I retarget invite requests to an application endpoint, but failed because of the timeout while accepting the incoming call. The exception details are as follows:
Occured an error while accepting the call. Detail: Microsoft.Rtc.Signaling.Opera
tionTimeoutException:This operation has timed out.

The incomming call state has change from Terminating to Terminated
And the following pictures tell us the reslut of analyzing the log files:
Front-End Server: FEServer.bjdev.com/pool.bjdev.com
App Server: exchange.bjdev.com
I have been confirmed, all of the firewall have been closed. What could be the reason lead to accept incomming call timeout?
