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.

2020-10-05 1 min read Microsoft Teams
Problem While i was configuring an Audiocdes SBC with Direct Routing setup and started testing, we faced the issue that every call outgoing is presenting Anonymous as caller ID.

Solution After some digging, i found that the Privacy ID is added automatically when you enable the option -forwardPAI $true (P-Asserted-Identity) within the Set-CsOnlinePSTNGateway cmdlet. Because i don’t want to remove the PAI, i created the following manipulation rule in the Audiocodes SBC to remove the Privacy ID. Continue reading
