Action
Check all required Communication Server 1000 resources
(packages, license, and Communication Server 1000 patches).
Check the DN, telephone TN, and PCA configuration.
Verify that AST, IAPG, and CLS (CDMR/TR87A) are configured
correctly (SIP CTI only).
Verify that the AML Link status is up. Make sure that the ELAN ID is
greater or equal to 32 (SIP CTI only).
Check the SIP CTI status (on the Signaling Server, under PDT, issue
the command SIPCTIShow). Make sure the SIP CTI status reads
Application status: Active (SIP CTI only).
Check the DNS on the Signaling Server.
Verify the Signaling Server SIP and the MCM endpoint registration
on the NRS.
Ensure that MCM is registered to the NRS.
Verify the MCM configuration for the Called Phone Context and
check it against the Signaling Server configuration for the SIP URI
map and Private/CDP domain name parameter (SIP CTI only).
Verify the Routing, Host Authorization, and Certificates inside OCS
servers and Pool.
Note: Improper configuration of Routing, Host Authorization,
and Certificates on OCS Servers and Pool is the primary reason
Converged Office does not function properly in the Enterprise
Edition configuration.
If the problem still exists, go to the section Capturing traces and
