Hey list !<BR>
<BR>
I'm getting the feedback of a customer that a conversation is like half duplex : when he talks, the other end of the call is no longer heard.<BR>
<BR>
What could be the cause of these drop-outs ?<BR>
<BR>
A call that is coming in from the PSTN is routed through an IVR-system to the correct internal SIP-phone (Grandstream GXP2020).<BR>
<BR>
Where do I start searching for this problem ?
