AE Services uses port 4723 for communicating between AE Services and Communications Servers. Because this port is disabled
by default in the AE Services Management Console, you must enable it.
Procedure
From the browser on your AE Services administrative workstation, log in to the AE Services Management Console.
From the main menu of the AE Services Management Console, select Networking > Ports.
On the Ports page, under DMCC Server Ports, locate the TR/87 Port, and select
the option Enabled.
