System with double redundancy

One of our Clients designed the system with double redundancy. Short overview of such type of system

Pros:

  • No single point of failure
  • Client’s PBX has additional layer of redundancy with 3rd Asterisk in a case if main cluster under Virtual IP gets down

Cons:

  • Not usable with end-devices like softphones/phones which can only register to one server (can only be used with main cluster)

Notes:

  • 3rd Asterisk server should not be used when main cluster is operational (it should have lower priority in the routing table)
