Have you looked at the SIP trace to see what is going on? Also a tshark or tcpdump would let you see if media is flowing.

Hi,

when I call a Grandstream GXP2160 and pick up the call then I can't hear anything. Nothing is going in or out. Its just silence. Registration works, calling and receiving calls works too.

Other Phones work. xlite and snom D725

Does anyone know?

Thank you
