i use the monocle gateway for Grandstream GX3500-Encoder und a Reolink MP420 5MP . But now i got Problems with a Hosafe Dome Cam 1080P using the Sub-Stream with resolution 640x352 and no audio.

The Echo 5, Echo 8 and also the fireTV is closing the connection after receiving the SDP-Setup.

I can see this in my log-file.

SDP-Setup see below, could you give me any information what’s the reason for hanging up ?

What part of the SDP was not liked by the Echo’s ?

Thank you in advance

Thanks Andre
