Is the downgrade of a firmware required also for DT-24+?

Although DT-24+ can be used by Ver3.1, it is impossible to use by Ver.3.0. Is a cause in a firmware? Is any setup required?

Thank you for your help.

Re: Is the downgrade of a firmware required also for DT-24+?

If you have the DT-24+ running firmware for CallManager 3.1 and you want to downgrade it for use with CallManager 3.0, then this has been asked before. You can read the old thread here:
