Audiocodes MediaPack Loses Static IP Address

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.
