We are testing service records with Adtran 900. They work as intended, but what I am having issues with is understanding the failback behavior.
If the Adtran registers to the primary everything is fine. If we block access to the primary I can see the line register on the fail over SBC as expected. Looking at the PCAP I see nothing out of the ordinary with it failing to the backup. The problem I am running into is the Adtran always tries the primary first, regardless if that is where the line is currently registering too. Am I able to program the failback behavior? I don't want it failing back right away, but would rather wait to ensure that the SBC is stable. Typically, with a lot of other end points I can configure how long I want it to remain active on the backup, and I'm hoping I can do something similar here.
Thanks,
Trevor
