This looks like you have an IP routing issue.

The ip path has to be available in both directions
between the phones/IP Comm

Looking at your port triggering
You have only set the UDP for 16384.
You need to use the full range 16384-32768
as the ports are randomly selected by the call manager.

You also need to check that there isan IP route from
the other end IP subnet to your IP Comm subnet.

Hope this helps
