Upgrade to SRST 9

[mightyking]

Hi Experts,

I need to upgrade the SRST from 7.1 to 9.0. Do I need to upgrade the IOS version or just the SRST. Could someone please send me the detail on how to do so.

Thanks,

MK

SRST is the same as CME, it's directly tied to the IOS version, you cannot upgrade them independently.

There are many guides on cisco.com on upgrading IOS

Thanks Jaime,

That's what I thought. It seems we need to use SRST Manager as of version 9.0, is that right? In order to have SRST version 9.0 we need to move to 15.2, right?

Thanks,

MK

No, SRST-M is optional, as for version
