3. Locate the phone and select it. (one left click)

4. Select "Phone Details" if it did not automatically come up after selecting the phone.

5. Within the "Phone Details," you will see "Model Type:" where it should say, "Cisco Remote Phone-VPN Enabled"

If the phone is not built as a VPN enabled phone, you will need to delete the phone and rebuild it as a VPN Phone. The

phone will need to be staged on a CallTower hosted circuit, switch, or ASA before being sent to the remote location.

This is so the device can grab a VPN certificate.

Confirm VPN is Enabled.

1. On the Phone press the settings button.

2. Select the "VPN" option from the applications menu.

3. Confirm VPN is turned on.

4. If this is turned off press the "On" soft key

5. Press exit.

Physical Equipment Troubleshooting:

1. Confirm that the Ethernet cable is plugged into the correct Ethernet port on the phone (looks like 3 computers

connected) and the other end is plugged into your network.

2. Swap out the port being used to connect to your network.

3. Swap out the cabling being used with the phone.

4. Verify the DNS server is an outside public DNS server. If the DNS server is local, turn off DHCP to statically set an

IP address on the phone. You should use the same IP address, subnet mask, and default gateway as you

previously used. Set the DNS server to 8.8.8.8 and hard set the TFTP server.
