Secure conference does not work: Conferencing Oper State: ACTIVE_IN_PROGRESS - Cause Code: TCP_CONN_ERROR

Hi all

I configured a 2911 router for secure conferences, sccp admin state is up but i got TCP connection error. We are using CUCM v8.5.1.

When I telnet on port 2443 to our CUCM (through gi0/0 - phone vlan) it is able to establish the connection thus firewall/routing doesn't seem to be the prob.

sh sccp shows:

I created the trustpoints, imported via terminal the CUCM certificates / created a self-signed for the router.

Then I exported the router certifcate and uploaded it to our Publisher.

I configured enhanced conference bridge (encypted mode).

Everything else except conference calls are working - any idea?

Thanks and regards

Secure conference does not work: Conferencing Oper State: ACTIVE

I've been unable to fix it yet - still need help. Does nobody have an idea?

In most cases it seems to be a routing / firewall issue. I am quite sure that it isn't that kind of problem over here..

Hi Johass,

Not sure if you checked out this great link secure conferencing:

https://supportforums.cisco.com/docs/DOC-8197

It covers the registration troubleshooting as well. Let me know if it still fails and we can try and take a deeper dive into it.

HTH.

Regards,

Harmit.
