Hi,reviewing the CUC system requirements document, I notice that you need at least 8.0(3) version for virtual machines (and you're trying with 8.0(2)).See:http://www.cisco.com/en/US/docs/voice_ip_comm/connection/8x/requirements/8xcucsysreqs.html#wp26...
do we have any additional information for a solution? anyone ? I have the same issue (ENOTCONN error) on 2811 running 12.4.4-12.4.13a ip-base IOS.Connectivity, tacacs key and ACS(3.3) double checked already. Thanks.
