[cisco-voip] Phone VPN

[Brian Meade (brmeade)]

James,

The ASA certificate needs to be added as a Phone-VPN-Trust under OS Administration->Security->Certificate Management.  You then select that certificate under the VPN Gateway configuration in CUCM.  You then associate the VPN Group and VPN Profile to the Common Phone Profile and associate the Common Phone Profile to the phone.

If you're doing username/password authentication, that's all you have to do.  The certificate for the ASA will be in the phone's config file.  Just need to reset the phone on-site so it can download it.

If you want to do MIC-based authentication, you need to add the Manufacturing CA Trust certificate from OS Administration to the ASA as a trustpoint.

If you want to do LSC-based authentication, you need to add the Publisher's CAPF.pem certificate as a trustpoint on the ASA and Install the LSC on the phone.

Afternoon all,

We are trying a proof of concept here for Cisco IP phone VPN and are stuck, as we don't seem to be able to update the 9951 SIP phone we are using with the certificate needed to build the VPN tunnel.

The phone has been added with a 'common phone profile' but we cannot see where the certificate has been installed (if at all)

Versions are as so:

Cucm: 8.6.2
Asa ver 9.1(2)
9951 phone load: sip9951.9-3-4-24

Can anyone shed any light on what the correct process is to update the phone?

Kind Regards

James
