How to – Install a custom security certificate on MPP devices?

[Geovani]

1. Login to http://IP_ADDRESS_PHONE/admin/advanced
2. Navigate to Voice --> Provisioning --> CA Settings
3. Input the Custom CA Rule, pointing to the certificate (in the example below, we are pointing to EDOS
   

You can also configure a Custom CA Rule via the xml file by using the below parameter as an example:

<Custom_CA_Rule ua="na">https://webapps.cisco.com/software/edos/callhome/rootca?id=xxx</Custom_CA_Rule>

Hello

How can I access to http://IP_ADDRESS_PHONE/admin/advanced ?

This site can’t be reached

Hi there, 

Try https see if makes any difference. 

If http or https does not work, then web access might have been disabled.

<Custom_CA_Rule ua="na">https://webapps.cisco.com/software/edos/callhome/rootca?id=xxx</Custom_CA_Rule>

Note the service has been moved to https://software.cisco.com/software/cda/callhome/rootca?id=xxx

Hi, 

the link above is an example only. You can download the client certificate bundle from CDA https://software.cisco.com/software/cda/home, or you can also upload your own custom certificate to CDA and get your own link to configure the phones with (you'd get a link similar to the one shared on the above post)
