hello everyone
recently,our customer tell us they IPCC always can not connect the phone:when PSTN user dial the number to the ipcc they can hear the IVR,but when they connect to the agent,they only hear the ringtone,and then when agent off-hook the call will disconnect.
we check our system ( our use ICM and CVP 8.0),find that the CVP have some error, like this
6402: 10.10.10.21: Oct 26 2012 11:38:08.640 +0800: %CVP_8_0_SIP-3-SIP_CALL_ERROR: CALLGUID = 9B24C08F1000013A6121F2640A0A0A15 LEGID = 67AA3E26-1E5311E2-982FC60A-7D21DE10 - [INBOUND] - ABNORMALLY ENDING - SIP code [408], Reason Hdr [SIP;cause=408] Request Timeout, GW call using SURV TCL flag [false], NON NORMAL flag [true], USE ERROR REFER flag [true] with AGE (msecs) 80625 and Call History : 123456789132|-1;60107|1; [id:5004]

we already disable the CVP's NIC offload,like this:
and in regidit add new key
and disable the NIC config offload
the CVP we install on the VMware ESXi 4.1.0,260247
but the problem still exist
