Hi everyone,
Assuming you have SIP SRST in place as a backup to your CUCM 11.x cluster, what are the steps necessary to migrate from SRST to ESRST?
From what I can tell in configuration guides, it's just a matter of changing the mode to esrst under "voice register global".
1) What of configurations on the SIP trunks to the SRST, or within CUCM itself?
2) How would the admin select which directory numbers are being automatically synced between CUCM and the ESRST? Is it automatically infered based on SRST reference within the device pool?
3) Is the SRST licensing on the ISR 4k enough, or some other licensing/module necessary?
4) Are there any step by step guides or videos which show how to configure ESRST across the board?
Thanks!
