Release ports for estos products – which network interfaces are used?
August 2023
This article explains which ports must be released for the respective estos product components.
Under "Direction" there is
- "in" for incoming connections on the computer of the program itself
- "out" for the port that is addressed on the computer of the target program
Example: The UCClient connects "out" to the UCServer on 7222. This is the port that must be accessible on the server.
Usually, the port number for "out" is searched for and set by the TCP stack itself and cannot be specified/changed on the computer of the program itself.

Since ProCall 7 Enterprise the port number range can be restricted individually (properties of the SIP management group in the "Media" tab).

Procall Analytics
Analytics WebService
Port number | Transport | Direction | Purpose |
|---|---|---|---|
8732 | TCP | in | Access via web client The port used in each case is configurable or visible in the administration interface. |
Typically, a corresponding rule is set up in the Windows firewall during the installation/configuration of ProCall Analytics. This allows the process to access all ports on the application level. When using a different firewall solution, this rule may need to be set up manually.
Since some of the ports used by Analytics are allocated dynamically, only general statements can be made here. Other ports may be used in the respective customer environment. The port currently in use is visible in the Procall Analytics Server Administration under "Diagnostics" and can also be changed there.
