CUCM Certificates with Exchange servers

Hi,

Does any one know how to add certificates in CUCM 6.1?

Requirement: I need to add the secured SIP trunk between CUCM & Exchange server. If not wrong CUCM need to trust Exchange server so we need to add certificates to the CUCM

Regds,

You add certs using the CM Platform, aka OS Administration web GUI.  Once logged in, it's Security > Certificate Management > Upload Certificate.

Re: CUCM Certificates with Exchange servers

The certificates you see uploaded are created during CUCM installation. They are the various self-signed certs for the components of the CUCM sub-systems. On the Exchange side, I believe you would need the root CA certificate which can be either self-signed (customer has their own CA) or from a 3rd-party.

I need to know is there any specific certificate need to be upload for creating the SIP trunk between CUCM & EXchange Server.

In my client CUCM server, i see couple of Certificates already uploaded  like CAPF Trust, callManager trust,ipsec & tomcat with particulay in ".PEM file " & " DER file"  . So which certificate i should be using for SIP trunk between CUCM & Exchange server. Where can i get it downloaded from?

Re: CUCM Certificates with Exchange servers

Do i need to upload CTL along with CA root certificate?

I referred to Security guide for OS admin guide, in it theyhave mentioned to upload Certificate , upload CTL & Upload Directory Trust Cert.

So do i need to do upload "Directory Trust " & CTL  ?

Also, in this document  says to download CTL from OS Admin > security > Certificate managemnet

But i believe we can download it from Plugin ?

IN CUCM 6.1, i do not see options for upoloading CTL or Directory trust. Only i found option for Upload Certificate, so how come its mentioned in document ?
