Hi experts, there is a need to encrypt voice traffic and I have moved CUCM to mixed mode and assigned secured profile for Jabber & Hard phones. Would like to check on below items,
- the gateway is currently using mgcp, do I need to reconfigure for SIP TLS?
- how does Jabber & 8800 RENEW their identify certs ? Anything needs to configured?
The CAPF Service Parameter "Duration Of Certificate Validity (in days)" has a default value of 1825 or five years. It would be fairly unusual to generate a certificate for longer than that. The longer the RSA keys are in use the greater theoretical chance they can be compromised.
