Hello,
I have a doubt. I have an router for my voice data (I don't have access to its). But I know that the ip is 192.168.1.x with the vlan 1 and the default gateway is 192.168.1.x
I have an layer 3 switch, which is connect to my server ip-phones and is connect to my layer 2 switch for all my ips phones. All this is in vlan 80.
All my phones is connect to my server, a mean, I can call from each phones but internal, not external. Not outbound call.
Please check the image attached.

Thanks. This helps. Yes many of the 800 series routers do have interfaces that act as switch ports. This is verified by the fact that the router has vlan 1 interface. It looks like you have the address configured on the vlan 1 interface to communicate with your switch. And the dialer interface should communicate with outside. Are there any other interfaces on which you want to configure IP addresses?
You have two static default routes and that is a bit of a problem. You should remove this one
ip route 0.0.0.0 0.0.0.0 190.191.240.2
and you should replace it with a static route for the subnet that you will use on your switches for your phones etc.
The vlan mismatch is not a serious issue but it would be nice to clean it up. I see here what is configured on the router interface. Could you post the config of the switch that connects to that router interface?

But, i dont understand that:
"and you should replace it with a static route for the subnet that you will use on your switches for your phones etc."
Thanks,

Thank you for posting the config of the switch. It answers a question and it raises a couple other questions. You identify the switch port connecting to the router as 3/0/14 and it is configured as a trunk. It is not quite clear which router interface you connect to, but that may not be important because all of the router interfaces are configured as access ports. So you have a trunk port connecting to an access port. I believe that this is the cause of the error message about mismatch. I suggest that you change the switch port to be an access port, or perhaps even better as a routed port. That should resolve the mismatch messages.
The other questions include these:
1) you have configured the router with this address 190.191.240.1. So I would expect that on the switch you would have some interface configured with 190.191.240.2. But I do not see any interface with an address that comes close to matching the address used on the router.
2) On the switch you have two vlan interfaces with IP addresses. One is vlan 100 and the other is vlan 199. I assume that one is for the phones and the server. But which one is that? And what is the other vlan for?
3) once you have clarified which vlan is for the server and phones then we will know which subnet you need to configure a static route on the router.

Hi.
Vlan 199 is for the phones. Vlan 100 is for other project.

No, sorry. interface GigabitEthernet3/0/14 -> it's connect to other layer 3 switch. Port 13 is connect to router.

Hi,
I have connection from the switch is connect to the router but I can't do ping from the server to the router.
I did a no switchport and put an ip on the interface 3/0/13 on the swtich, but not connection.
