OCS Relay FindMe™ users fail to register.
If OCS Relay fails to register FindMe™ users (Registration status = failed), check:
1. The FindMe™ name is correctly entered into Active Directory.
2. A MOC client can register as the FindMe™ name.
3. The Cisco VCS SIP registration proxy mode is set to ProxyToKnownOnly (or ProxyToAny).
4. That there is no transform that may be inadvertently corrupting the registration – e.g. appending
an @domain to a name which contains no @ (as registrations proxied to OCS have a URI which
is the domain only - no @).
5. Check cpl is as defined in the ‘OCS Relay configuration of “OCS gateway” Cisco VCS(s)’ section.
6.
Check that the zone details have been updated as defined in ‘OCS Relay configuration of “OCS
gateway” Ci
sco VCS(s)’.
Troubleshooting OCS Relay
OCS Relay produces an event log file that contains useful information about its operation.
This is only available through root login to Cisco VCS. It is a big file and so it is usually best to ‘tail’ the
file to look at the last few entries.
To view the last 300 entries of the OCS Relay log file:
1. Login as root on Cisco VCS
2. Type:
tail -300 /mnt/harddisk/log/elbe.log
OCS problems
As a starting point, running the OCS ‘Best Practices Analyzer’ will help identify configurations that may
be incorrect on OCS. Details and the download may be found at:

OCS running on Microsoft Server 2008 R2
Operation of TLS has been changed in this version of Server software – this version is not
recommended for use.
OCS stops running after an upgrade
Ensure that Automatic upgrades are turned off. There are occasions when an upgrade comes through
which will affect operation of OCS. Check the validity of the upgrade before installing.
Do not install upgrade KB974571.
Problems with certificates
If a non-OCS application is used to create certificates to load onto Cisco VCS for use with OCS (e.g.
purchased from a certificate authority) it is vital that the Subject name and Subject Alternate Name
contain the same details as they would if the certificates were created by OCS.
Specifically, if both Subject name and Subject Alternate Name are used, then the name entered in the
Subject name must also appear in the Subject Alternative Name list.
