I'm wondering if it's possible to set up configure TFTP redundancy for CCM 5.1.
We ran into an issue yesterday that didn't work as I thought it would.
I currently have 2 CCMs (one pub, one sub) and 9 remote sites. Under option 150 for the remote sites, I configured the IPs for the pub/sub(10.50.0.10,10.50.0.11). By default, all phones are registered with the Subscriber. I was under the impression, during the failure of the subscriber the remote sites would attempt to re-register with the Publisher before failing over to SRST. During my failure yesterday, the remote sites failed directly to SRST. I was able to get the phones to register with the Publisher by changing the TFTP order under option 150.
Am I missing something for the redundancy to work? Failover did work as intended for any phone not using SRST.
