Can LSCs be automatically updated before expiration?

[Nadav]

Hi everyone,

If I have 79xx phones deployed, in a mixed-mode CUCM 11.x cluster, is it possible for their LSCs to be renewed automatically without my intervention? Is there an enterprise/service parameter that needs to be set?

Thanks!

[Jonathan Schulenberg]

Nope. This is one of the problems with CAPF as it currently exists: an administrator must trigger the renewal operation either through a BAT job or on an individual device.

Thanks for the quick reply.

Any chance that some API or other interface exists to extract that kind of information from the CUCM?

I can tell when various certificates on the CUCM are set to expire via CLI, including CAPF, but I presume that each LSC has its own expiration date according to when it was signed.

I believe only 11.5 has some new reports regarding certificates to make this tasks easier
