Avaya IP DECT Master and Standby Master and trunk to CM

[OlegPowerC]

Hello!
Can You explain me next:
I configured 18 DECT stations, one of this is Master and one Standby Master.
I configured H.323 trunk to Master and H.323 trunk to Standby Master
But in XMOBILE station I provide one mobility trunk group.
How I can do redundancy?
Thank You!!!

Hi collegues.
I am complete task:
After master is down (I am disable PoE to it), standby master goes to active.
Then after 3-5 minutes, I check trunk group to this master (status trunk 2) and see Out Of Service
In my XMOBILE stations, field Mobility trunk group was 2 and after trunk 2 goes down, it field automatic changed to 3
I do not totaly understand how it work but it work.
My DECT setup:

Thank You!
