Option A is correct here. SRST lets phones reregister automatically to the publisher when connectivity to the subscriber fails. Device Pool just groups settings, doesn’t handle failover directly. Seen this a lot in practice configs.
A is right, it's SRST for sure. Device Pool just handles grouping settings, not actual failover or reregistration. Easy to mix up since device pools set call manager groups, but SRST is the one that provides survivability if the sub drops. Agree?
A tbh. SRST is designed exactly for this scenario-when phones lose connection to a subscriber, they use SRST for fallback and will reregister to the publisher once it's back. Device Pool just applies common settings, it doesn't enable auto-reregistration.
Maybe D. The Device Pool sets call manager groups, so it seems like phones would failover that way. Clean question format.
Be respectful. No spam.
