Cisco Routing Issue - 4 switches + PIX, traffic not passing between switches

I've got a really odd issue that I'm sure has something to do with routing, but I don't know enough about the Cisco equipment to figure it out yet!  We have...

Cisco PIX 515 whose inside interface goes to a 16 port unmanaged Netgear switch
That 16 port unmanaged switch goes to:
  - Netgear 8 port unmanaged switch with servers
  - Cisco UC520 phone system (only using internal ports, so should just function as a switch with a voice VLAN added)

The UC520 goes to a CE520 8 port Cisco Catalyst switch.  Traffic can pass from clients behind the CE520 to the servers, but can't get out to the internet.  All other clients can get out to the internet.  

The PIX can ping the UC520, but not the CE520 switch.  The UC520 can ping both the PIX and the CE520 switch, so I would imagine there's some sort of routing issue with the UC520 configuration.  Here's the relevant config portions for it, cleaned up...

without a network map, the config is troublesome to read...

But, if I make some assumptions, you'll correct me I hope...

Your default route is 192.168.3.100, and that subnet is assigned to vlan1, but I cannot see any ports assigned to that VLAN..

What particular port is the CE520 hanging off the UC520 ?

Debuggerau - sorry about that...the PIX sitting at the edge of the network has an inside interface with 192.168.3.100.  Vlan1 is data, 192.168.3.0/24, vlan100 is voice, 10.1.1.0/24.  The CE520 is on the uplink port of the UC520 (0/1/8) and the gigabit uplink port on the CE520 (Gi1).  Both of the smartports are in switch mode for them.

Devang - all the voice devices are on Cisco PoE switches.  It's the servers that aren't, but they shouldn't need to be.  The only issue is getting data from the managed switch behind the UC520 out to the internet.

Devangshroff, you were correct.  Apparently it didn't matter that the unmanaged switch wasn't in the direct route to the internet.  We replaced it with a Catalyst 2960 and everything came right up.  Thank you!
Your help has saved me hundreds of hours of internet surfing.
