Audiocodes MediaPack Loses Static IP Address

Posted by erwin on Tuesday, January 29, 2019

By default the Audiocodes MediaPacks, sent out a BootP request during a cold start of the device. If you have a enterprise DHCP server active in the network this will probaly respond (undesired) to this request and will give you a DHCP release from the DHCP pool. This way the MediaPack will receive a new IP address from the DHCP pool everytime it will have a cold start.

The setting ‘BootPSelectiveEnable = 1’ enables the device’s integral BootP client to filter unsolicited BootP/DHCP replies and accepts only BootP replies that contain the text ‘AUDC’ in the vendor specific information field of the request.

In the picture below you will find the cold boot flow from the MediaPack.

Solution

To prevent losing the configured IP address due to BootP/DHCP request on a cold start you will need to perform the following steps:

  1. Save the current configuration INI file to your PC

  2. Open the INI file and go to the [SYSTEM Params] section.

Add the following line:

BootPSelectiveEnable = 1
  1. Save the file and upload it to the MediaPack. The MediaPack will reset automatically after the upload.
