Re: CTI OS Desktop Recording

Hi Hakim,

the error message is quite a generic one.

To qualify this try to answer the following:

This affects one agent, not all agents, right?

Does this message appear every time the supervisor tries to monitor this agent?

What version of IPCC and CTIOS are you using?

Are the agents on a different network than CTIOS? If so, are any firewalls or NAT being used between them?

Port 8500 needs to be open.

What type of NIC is being used on the agent's desktop?

What OS is the agent using?

To provide some general guidance:

Qualifying Ethernet Cards for Cisco Agent Desktop Monitoring

Agents Cannot be Changed to Silent Monitor Status Unless They are Logged in as an Administrator

Cisco ICM Software CTI OS System Manager's Guide, CTI Software Release 6.0(0)

(Appendix A: Testing an Ethernet Card for Silent Monitor)

And as suggested, do some testing on the other Supervisors configured to try and narrow down the scope of the problem, to determine if this applies to all supervisors or just a few.

On the troubleshooting side, try to reinstall the supervisor desktop and confirm the registry

Check registry on Desktop:

H_KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF Start = 0x0000002

Finally try also to uninstall WinPcap 3.0 and install WinPcap 3.1 from



PS. Please rate useful postings accordingly and raise a TAC case if you need extended troubleshooting

Hi Hakim,

check on this agent, try remove/readd him from the config, check on his network card, see if the registry is not set to send flagged packets and so on.

I guess you are on the right track to fix it, consider eventually removing the software and reinstalling it on his PC, WinCAP included.

Re: CTI OS Desktop Recording

Check the CTIOS logs on the agent PC to see if you get a message saying AcceptSilentMonitoring. If you do try some of the following.

1. If CTIOS log show monitoring port as 8500, check to make sure a firewall isn't blocking it

2. Make sure the router or switch isn't blocking UDP 8500

3. There are know issues with NIC driver versions stripping the VLAN tag. Try upgrading the NIC driver.
