Checking Remote Call Control (SIP CTI) configuration

Checking Remote Call Control configuration

Step Action

1Check all required Communication Server 1000 resources (packages, license, and Communication Server 1000 patches).

2Check the DN, telephone TN, and PCA configuration.

3Verify that AST, IAPG, and CLS (CDMR/TR87A) are configured correctly (SIP CTI only).

4Verify that the AML Link status is up. Make sure that the ELAN ID is greater or equal to 32 (SIP CTI only).

5Check 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).

6Check the DNS on the Signaling Server.

7Verify the Signaling Server SIP and the MCM endpoint registration on the NRS.

8Ensure that MCM is registered to the NRS.

9Verify 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).

10Verify 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.

11If the problem still exists, go to the section Capturing traces and logsto assist further.
