WFO ACR - no such TLink error

[gavinchan]

I am installing v11.0-2patch110014. ACR on windows 2008 R2 64bit.

Always get the following error:
Link to CTI on 10.0.8.83 reporting error: no such TLINK
Link to CTI on 10.0.8.83 reporting error: Not available
Recorder fatal error: Main CTI feed

since I tested my old ACR 10.1 without any problem using the conference mode recording. so I believe the AES and CM are set up properly.

any suggestion?
or what should I input in the AES TSAPI Server(s) and AES TSAPI Switch Names(s) parameters. since the wording for these 2 parameters are actually different from 10.1.
10.1 askes you to input the TLink directly, while v11.0 doesn't not.

thanks!
