Cisco 2800 - IPPhone issues

[matteociaschini]

I have a Cisco 2800 router.

The Interface FA0/0 is connected to internet with a fix IP.

Interface FA0/1.1 isuse for the local data network.

Interface FA0/1.2 isuse for the local voice network.

Ports FA0/3/x are used to connected the IpPhone.

Router is connecting to internet and VPN is closing correctly.

FA0/1 is connected to a switch and computers connected to it can go on internet and reach the VPN.

The problem is with the Phone connected to FA0/3/x ports.

They are not getting IP in automatic so they are not registering.

If I connect a PC to one of this port, it get the IP but I'm not able to access any network (local, internet or VPN).

I tried to configure port in trunk or access mode without success.

In attachment running config.

Do you have any suggestions?

Thanks,

Matteo

In looking at the config that you have posted I notice that on the interfaces of FastEth0/3/x all but two are configured with switchport mode trunk and then a voice vlan statement. I would suggest that you configure all these interfaces as access ports in vlan 1 with a voice vlan of vlan 2.

Hi Rick,

thank you for the replay.

At the beginning I had all the ports set in trunk.

I now set all the ports like following

interface FastEthernet0/3/0

switchport voice vlan 2

auto qos voip

But I still have the same problem.

If I connect a computer to one of the the FA0/3, it will not find DHCP too.

Thanks

Matteo
