[cisco-voip] CUMA and ASA as Proxy

[Ryan Ratliff]

For lab purposes you *should* be able to get it to work.  It's not  
TAC supported but that really doesn't matter for a demo.  I also  
believe Verisign has temp cert you can get for free (but it has an  
expiration date).

Regarding the name, it needs to match whatever you populate in the  
external DNS, which should resolve to the ASA.
"Obtain the IP address and fully qualified domain name for the Proxy  
Host"
The proxy host is your ASA.

I have a procedure on how to make the self signed certs work on my

That is the least of my problems or concerns. If it does not work that's
fine but I have to try. We are only looking at a pilot of about two  
phones.
If we do a customer deployment we will have them get a correct cert.

In the below step do I create the cert using the name of my Cisco ASA  
or of
the name of my CUMA server?

For New Installations) How to Obtain and Import the Cisco Adaptive  
Security
Appliance-to-Client Certificate
This procedure is required unless you are upgrading from Release  
3.1.2 and
reusing your signed certificate from your Proxy Server.

This procedure has several subprocedures:

.Generate a Certificate Signing Request

.Submit the Certificate Signing Request to the Certificate Authority

.Upload the Signed Certificate to the Cisco Adaptive Security Appliance

Generate a Certificate Signing Request
Before You Begin

.Obtain the IP address and fully qualified domain name for the Proxy  
Host
Name as specified in Obtaining IP Addresses and DNS Names from IT,  
page 1-3.


.Determine required values for your company or organization name,
organizational unit, country, and state or province. See the table in
Creating Security Contexts, page 9-7. You must enter identical values  
in the
Cisco Adaptive Security Appliance and in the relevant security  
context in
Cisco Unified Mobility Advantage.

Procedure


------------------------------------------------------------------------

Step 1 Enter configuration mode:

conf t

Step 2 Generate a key pair for this certificate:

crypto key generate rsa label <keypair-cuma-signed> modulus 1024

You will see a "Please wait..." message; look carefully for the  
prompt to
reappear.

Step 3 Create a trustpoint with the necessary information to generate  
the
certificate request:

crypto ca trustpoint <trustpoint-cuma-signed>

subject-name CN=<Proxy Host Name of the Cisco Unified Mobility Advantage
server. Use the Fully Qualified Domain Name.>,OU=<organization unit
name>,O=<company or organization name as publicly registered>,C=<2  
letter
country code>,St=<state>,L=<city>

(For requirements for the Company, organization unit, Country, and State
values, see the values you determined in the prerequisite for this
procedure.)

keypair <keypair-cuma-signed>

fqdn <Proxy Host Name of the Cisco Unified Mobility Advantage server.  
This
value must exactly match the value you entered for CN above.>

enrollment terminal

Step 4 Get the certificate signing request to send to the Certificate
Authority:

crypto ca enroll <trustpoint-cuma-signed>

% Start certificate enrollment.

% The subject name in the certificate will be:CN=<Proxy Host Name of the
Cisco Unified Mobility Advantage server>,OU=<organization unit
name>,O=<organization name>,C=<2 letter country  
code>,St=<state>,L=<city>

% The fully-qualified domain name in the certificate will be: <Proxy  
Host
Name of the Cisco Unified Mobility Advantage server>

% Include the device serial number in the subject name? [yes/no]: no

% Display Certificate Request to terminal? [yes/no]: yes

Step 5 Copy the entire text of the displayed Certificate Signing  
Request and
paste it into a text file.

Include the following lines. Make sure that there are no extra spaces  
at the
end.

----BEGIN CERTIFICATE----

----END CERTIFICATE----

Step 6 Save the text file.

I am going through this battle right now

As far as self signed certs the response from the BU was that they are
completely not supported as mobile phones do not do certs "well".  In
other words if you can manage to get the CA of your domain onto your
phone it might work for a week or two but then it might fail.  The BU
states that you need to use a verisign cert or GEOTrust.

Let me know if you need more help.
