Hi all,
I have a very strange issue. When put on hold by some called parties (does not affect all called parties, but can be reproduced with certain called PBXs) out local FreePBX play music on hold and the called party can still here us talking! I tried to trace this, but I do not see anything special coming from the SIP-Trunk.
x.x.x.x is the IP of the SIP-provider
y.y.y.y is the local IP-address
