I am running into an issue with configuring 7962 connecting to Call Manager over VPN Connection. I get VPN Authentication Failed with "All Concentrators Failed" error in Status messages.. Please look at the following config on ASA:
crypto ca trustpoint VpnPhone
crypto ca trustpoint CallManager.pem
crypto ca trustpoint CAPF.pem
crypto ca trustpoint Cisco_Manufacturing_CA.pem
I have uploaded certificates from ASA to Call Manager and from Call Manager to ASA.
The first place to look would be the phone's console logs when trying to connect to the VPN. From there you will see if the phone is failing to connect or if it's a certificate problem between what the phone knows of and what the ASA is using.
Thank you for responding. I disconnect my phone from outside connection and plug it into LAN so I can pull logs. Once I pulled logs, I don't know much, but here is what I found might be useful? Please advise. Anything in perticular i should be looking for?
Do you have host ID check disabled in CUCM for the VPN configuration? The URL being an IP address will not match the certificate Common Name (CN). You should see if this is a problem from the phone console log too.
