Hello,
How JabberforWindows read the certificates?
The CUCM have been installed using DNS (name + Domain)
On the web configuration of the UC, The server are configured as IP addresses.
When we do a first deployment of the JW, for test, it asks if we will accept the certificate of the server or not.
The thing that we saw is like this:
On the warning message: it shows the IP address,
and when we read the certificate that its gets then it shows the FQDN name of the server.
Thus the certificate is invalid. Even if it is valid from the CA server, using the FQDN. Because CA server don't allow IP Address as CN.
How to resolve this issue?
If I wish to change the Hostname of the server in the CUCM ( i.e instead of using IP Address I'll use hostname+domain).
Then this will have impact on the endpoints. Because all 3000 endpoints will ask the DNS each registration timeout. This may have impact also the DNS server (DOS). etc.
Regards,
