Description (partial)

Symptom:
MRA Deployment guide needs to be updated with the missing steps for Activation code onboarding over MRA

Below are some of the steps omitted:
1.In Cisco CUCM Enterprise Parameters, Verify OAuth with Refresh login flow parameter is enabled
-Go to Cisco Unified CM Administration > Enterprise Parameters > SSO and OAuth Configuration

2.Check the cloud Onboarding page:
-To authorize the cluster (CCMAct service) to connect to the cloud-based device activation service, generate the voucher by clicking the Generate Voucher button.
-Check Enable Activation Code onboarding with Cisco Cloud*
-MRA Activation domain should be provided. MRA activation domain provided to Cisco Cloud to redirect phones to customer Expressway-E(s)**

*collab-edge DNS SRV record(s) need to exist for this domain
**One MRA activation domain per CUCM cluster

3.Create and manage MRA service domains under:
Cisco Unified CM Administration > Advanced Features > MRA Service Domain menu*

*There will be one system level default MRA service domain, plus the option to establish MRA service domains at the device pool and device level. The MRA activation domain can also be used as a service domain. Different service domains can be used to direct phones to regional Expressway C/E pairs


4.Check MRA access control on Expressway
-On Expressway C > Configuration > Unified Communications > Configuration
-Check Authorize by OAuth token with refresh is set to On
-Allow activation code onboarding set to Yes*

*Enabling Activation Code Onboarding forces the Expressway-E to request a client certificate for any connections to TCP 8443

4. Check Trusted Cisco manufacturing certificates (MICs) installed. They are required to access the activation code onboarding functionality
-On Expressway E > Maintenance > Security certificates > Trusted Ca certificate
-Click Activate code onboarding trusted CA certificates

Conditions:
Customer needs to Activate a bulk number of IP Phones over MRA

Ensure the device has been created, configured and activation codes enabled on CUCM (see CUCM configuration guide chapter on Device Onboarding via Activation Codes for versions 12.5.SU1 and above.)
