Standby SBC is Out-Of-Service and Not Coming Up after Several Reboots

(Doc ID 2121132.1)

Last updated on MAY 15, 2017

Applies to:

Integrated Software for Acme Packet 4500 - Version D-Cx1.0.0 and later
Information in this document applies to any platform.


After reboot, standby SBC goes out-of-service.

In this scenario, we increased becoming-standby-time (in redundancy-config) from 240000 to 320000, still standby system was stuck in 'becoming-standby" state and after that goes out-of-service.  We could see the health score as 100, but SIP and Media synchronization was set to false.


As SIP and Media synchronization were not being pushed from Active Server, Standby was going out-of-service.
