Summary:                    IAX trunk clicks as other calls in the same trunk
hang up
Description: 
We have 2 IAX trunks between head office and 2 branch office, over a 5Mbit
private ip network.

Each time a call hangs up on the same trunk as other calls, the other
calls hear an annoying click.

When a 2nd call joins the trunk, no clicks are heard.  

Call quality while talking is near perfect with so much bandwidth, we are
using alaw codec.
