•

At the end of the installation and configuration process, to test the solution and the 

integration with the OCS, create an ongoing conference with two participants, one dial-

in and one dial-out and connect them to the conference.

•

If  the  active Alarm “SIP TLS: Registration server not responding” is displayed, stop and 

restart the OCS Pool Service.

•

If the communication between the OCS and the MCU cannot be established, one of the 

possible causes can be that the MCU FQDN name is defined differently in the DNS, 

OCS and MCU. The name must be defined identically in all three devices, and defined 

as type A in the DNS. The definition of the MCU FQDN name in the DNS can be tested 

by pinging it and receiving the MCU signaling IP from the DNS in return.

•

The communication between the OCS and the MCU can be checked in the Logger files:
—

SIP 401/407 reject messages indicate that the MCU is not configured as Trusted in 

the OCS and must be configured accordingly. 

—

SIP 404 reject indication indicates that the connection to the OCS was established 

successfully.
