Setting up tag based routing in Audiocodes Mediant

2021-02-24 2 min read Audiocodes Microsoft Teams
In this post i want to show the configuration steps of configuring tag based routing. You can use Dial Plan tags for determining the destination (IP Group) of an IP-to-IP Routing rule. One of the advantages of using Dial Plan tags is that it can reduce the number of IP-to-IP Routing rules that you would normally need to configure. For example: When you have an SBC with SIP trunk and legacy PBX and you would like to implement Microsoft Teams Direct Routing you can route specific numbers to Teams and the rest goes automatically to the legacy PBX.

Audiocodes MediaPack Loses Static IP Address

2019-01-29 1 min read Audiocodes Erwin Bierens
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.
