CUCM Security - Are Jitter, Latency and Packet Loss Stats in Clear Text ?

[asafayan]

I've reviewed the Cisco Unified Communications Manager Security Guide and see no suggestion that implementing encryption prevents MoS scoring.  In other words, when you implement encryption, do you still have access to jitter, latency and packet loss information in clear text?

TIA,

Amir

CMR data AFAIK has nothing to do with authentication/encryption.

Thank you Jaime.

Well.. the phones measure the statistics.

The phones then report the stats to CUCM for inclusion in the CMRs.

... as I recall this is done via SCCP.

So yes, it's clear text, unless your signalling is encrypted generally. On most clusters it's not.
