I just got my first Xiaomi product (a Mi Max 3 and I love it!). However, I noticed that the quality of SIP calls is very choppy and cutting all the time.
I don't think the SIP calls are using the wifi network so maybe it explains why. Is there a way to enhance call quality/reliability of SIP calls ?
Just to let you know, my SIP has been configured both from inboud and outbound calls and I'm using TCP.

Thank you !
