Most calls with Teams Direct Routing become one way audio

Hi jguel, where is your SBC deployed? Is it nat'ted? In case there is NAT used: did you configure NAT rules on the SBC, too?
There is a good blog post regarding SBC Teams Direct Routing and NAT here: https://www.ucguys.com/2018/08/one-way-audio-with-microsoft-direct-routing-with-audiocodes-mediant-sbc-when-using-a-nat.html

I am having this issue with Audiocodes SBC but its after 15 min. Wondering if you were able to find a fix? jguel

You might want to check the IP Profiles and the Media Security settings for the trunks on the SBC.
