UC520 & Cisco 2821 voice problems

My current setup:


Linksys RV082 Dual Wan Router

|

Cisco UC520

|

Cisco 2821

|

Cisco Catalyst 3650g

|..................|

Phones.....Desktops


My problem is that when I plug in a phone to the Catalyst 3650g I get a configuring ip etc. loop. What I think I am doing wrong is not routing the voice trafic correctly through the 2821 router, or the router is not configured properly for the phone trafic.


The 2821 configureation is attached.


I currently have uc520 on default configurations for VLAN(100), and the catalyst 3650g switch setup for the phones voice trafic VLAN(100). All data flow on the network is fine.



Thank you for your help,

Michael Bernstein

I would imagine that you'd need an ip helper in order for the phones to get in contact with whatever is on the other side of the 2821.
