CUBE ISR G3 High Availability

Hello guys!
I am confused about ISR G3 CUBE high availability (box-to-box redundancy). I need to plan CUBE (ISR 4431) redundancy with calls preservation. Do these gateway serries support that function? I just saw some information about ISR G2 and ASR platforms, and i can't undrestand correctly do i need to redundancy group configuration or it must be a HSRP?
If it possible, please provide any references and explain which licenses i have to use at CUBE for the proper call preservation functionality.
Many thanks.

please note that call preservation will only work with media flow around. if your provider does not support that or if it is routing wise impossible to achieve than you are flogging a dead horse.

 

from CUCM to CUBES it is fairly easy to make it redundant by using Route groups and OOB pings. calls into your organisation is different as your provider will need to support it, so hook up with them first and have a discussion re. your requirements.

 

thx
