To update the port settings:

1. On the MiVoice Border Gateway main page, click the Network tab and click Port ranges.

2. Edit settings as required and click Save.

- The minimum usable port for any range is 10000.

- Ensure none of the ranges overlap.

Service | Description | Values
--- | --- | ---
MiNet and SIP audio port ranges
Field names: MiNet & SIP audio starting port MiNet & SIP audio ending port | Use the screen tools to set the range of ports available for use by MiNet and SIP calls. Use the following guidelines to calculate how many ports you require for MiNet and SIP calls: For a typical MiNet call with audio, four UDP ports are required: two for audio and two for RTCP voice. As a rule of thumb, we recommend that you open a number of ports equivalent to four times the number of devices in your system. For example, if you have 2499 devices (4 x 2499 = 9996), open 9996 ports (from the starting port of 20002 to the ending port of 29999). | Defaults: MiNet & SIP audio starting port is 20002 MiNet & SIP audio ending port is 29999
Call Recording port ranges
Field names: Call Recording starting port Call Recording ending port | Use the screen tools to set the range of ports available for use by the secure Recording Connector (SRC) on MiVoice Border Gateway. | Defaults: Starting port is 35000 Ending port is 35999

This application is running in a container solution, port ranges are configured during deployment. These port ranges are pre-defined. See your solution documentation for details.
