18700

First of many UDP ports responsible for external PBX voice session. Each new session uses a next port.

Multiple sessions might be initiated only during the Conference Calls. Dispatchers are unable to receive and process multiple phone calls.

Number of Ports

Recommended to allocate up to 20 ports to serve up to 20 voice sessions. More sessions may negatively impact the product performance.

Each new PBX call allocated its own UDP port starting from this port. When a session is over, that port is released and reused in the very next session.

Host Reference

The port shall be opened on the Dispatch Console.
