<p dir="ltr">Hi,<br>
I hope you already have fixed it . In case you didnt then here are my thoughts. Looking at the flow and keeping in mind that all devices are in same subnet you should never get one way audio issue since OpenSIP is not playing with SDP so Asterisk and PGW should just be able to have two way audio all the time and so you should debug the B leg going out to the endpoint. </p>
