Disconnection

Hi,

I have install in a notebook dell:
Linux, CentOS 5.2 (Kernel 2.6.18-92.el5)
Asterisk 1.6.1.5 (with Realtime MySQL)

When call from the Softphone X-Lite version 3.0 build 53,621 is reported correctly, but the connection is lost randomly cutting the call. The notebook linux (Pitagoras) has an Ethernet card: Broadcom NetXtreme 57xx Gigabit Controller

Ping from a PC a notebook Linux (192.168.1.52)
C:\ping -t 192.168.1.52
