Which phone load and CCM exact version?

Which are the settings for

Busy trigger and Max calls.

You may gather detailed CCM|SDL traces an sniffer trace will be useful also when problem occurs.

Re: A hard question

Set up Ethereal on a desktop or laptop and plug into the switchport on the back of the IP phone. This will let you see the RTP packets and any detail about them. You could also try the following settings:

Busy trigger: 2

Max calls: 1
