SRST Advantage with Clustering over IP

abbas.ali
Level 1
Level 1

If we are designing a cluster with one subscriber being in a remote Location. For remote location, Local subscriber can be a primary Call Manager, and backup Call Manager could be another subscriber in data center. Is there any need to have a SRST or CME-SRST in a remote location. I don't see any real benefit. The only time SRST/CME-SRST would have any significance if both Local Subscriber and the IP WAN go down at the same time.

it would really depend on the level of redundancy you want to have and the money you're willing to spend.

if you see a real possibility of your worst case scenario happening sometime then SRST would be a good option.

if you feel that at any time only one of the two scenarios you mention could happen then you might be covered

just take in consideration that depending on the amount of phones it could cause some WAN congestion if not properly sized
