How do I switch a ATA186 to SRST mode without disturbing other network services and devices?
I have to check SRST functionality (switchover & fallback) and I only have access to Callmanager 4.2.3, the Voice Gateway (H.323) and the ATA186 itself. The voice gateway isn't the default gateway and apart from SCCP signalling so I can't apply an ACL there. The other networking devices btw. CCM and ATA are not under my controll.
My first idea was to configute a static host route to ATA's IP on CCM.
But isn't there a less critical way to put an ATA into SRST. And how to put it back to CCM controlled mode?
