[cisco-voip] Cisco 8841 VPN phone issue

Thu Sep 10 13:35:18 EDT 2015

For those following along at home CSCuv49148 is no longer an enhancement.  Hopefully we’ll see a fix in the next release.

CSCuv49148 is for the phone firmware to allow the VPN to start up if the VPN feature is configured without requiring a TFTP to be set on the phone.

Any updates made to the configuration of the phone in CUCM require that the phone be brought inside the network for them to pick up the changes.

The 8841 should know that it has VPN configured and not switch to MRA mode when it boots on the home network that doesn’t have TFTP configured.  You can hard-code the TFTP on the phone by enabling alt-tftp but that should not be required.

If it works as expected with cert-based VPN but not username/password then this likely a phone bug.  Please open a TAC SR so it can be investigated further.

Would that require the phones to be reregistered on the local network before being used? I’ll uncheck the box, it’s possible it doesn’t match but I’m not 100% sure.

Thanks!

You may need to disable the Host ID Check if your certificate's CN/SAN doesn't match the VPN URL you're using.

Do you have Host ID Check enabled on the VPN profile?

You don't need any certificates on the ASA from CUCM for username/password to work.  Did you assign the certificate to the VPN Gateway in CUCM after uploading it to CUCM?

Joe, thanks for the recommendation. Here’s what we experienced:

We set the TFTP address to the local server and restarted the phone. It sat on registering and never changed or prompted for login. We looked and noticed we could now tick on the box to enable VPN and that prompted for a username and password. When we logged in we received an error message indicating an invalid certificate.

We uploaded the certificate from ASA to CUCM prior to configuring the phones. Since we’re using username and password we didn’t import any CUCM certs to the ASA, do we still need to do that even if we aren’t using certificate authentication?

Thanks!

The actual internal TFTP server address.  The phone will use it after the VPN connection is established to download its configuration file.

What should the TFTP address be set to for the remote VPN phone? The actual internal TFTP address or the VPN head end?

Thanks!

The prompt you are seeing with Service Name, Username, and Password is for the Mobile and Remote Access (MRA) feature.  More information about this can be found here - https://tools.cisco.com/squish/92527f.  In order for the phone to start the VPN sign-in process instead of the MRA sign-in process you must have a TFTP set on the phone, either via DHCP or manually.

Greetings!

I’ve setup a new server using 10.5.2 for VPN using 8841’s and username and password (not certificate). I followed the details in the following features configuration guide for VPN client.

http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/cucm/admin/10_5_2/ccmfeat/CUCM_BK_C3A84B33_00_cucm-feature-configuration-guide_rel1052.pdf

The phones were configured and registered on the local network so they got the VPN common phone profile information. When we try to use the phone at home it prompts to supply Service Name, Username and Password. What should the service name be? We searched for hours and didn’t see anything that related to a service name and we tried everything we could think of.

I am able to VPN using username and password with the AnyConnect client to the URL for the VPN phones that was setup. It’s an ASA 5512 and the proper licenses are applied. I checked the feature report on CUCM and the 8841 is supported. Unfortunately I’m not able to access the web server on the phone (I’ve tried to no avail.)

Any thoughts or ideas here?

Thanks!
Hank
