I had an incident this afternoon where 1/2 of our phones were stuck in "CM List" when trying to chnage to failback mode. We lost a circuit. 1/2 of the phones went into SRST while the other 1/2 tried but were stuck in CM list. Any idea what could have caused the 1/2 not to re-registed to SRST gateway?
Have you tested SRST on this router before where all phones have registered to the router ? how many phones are in question and how does your SRST config look like (call-manager-fallback - sub commands)
I was specifically interested in the sub-commands under call-manager-fallback mode. Have you limited the total number of phones to less than the total number of phones you have ? (max-ephones 3845 should support upto 720 phones.
3845s support upto 720 phones. The number of phones that can register is limited by the max-ephones command. What do you have set that to ? Also are you using a Class B or Class C subnet for that many phones ? A class holds only 254 addresses and you may have to create additional voice vlans, or subnets to supports phones more than 250. I am not sure if there was enough ip address left in your dhcp pool, that could have also caused the problem.

If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
