7921 wireless phones using load 1.1.1
CUCM is 6.1.2
7921 is connected to WISM OK and registered to CUCM PUB.
Device Pool has CUCM Group with sub first choice and pub second choice.
7921 registers to pub as primary and then uses the default gateway as second SRST choice(default gateway is just a vlan interface hsrp address)
The Device-Pool has SRST ref disabled.
Doesn't matter what callmanager group/device pool I use it is always registers to pub and default gateway under the phone callmanager setting, even the Device-Pool with a SRST reference. Doesn't matter what order of CUCM I have.
Browsing directly to the 7921 IP address does say to use default gateway as SRST but this cannot be altered.
I even enabled TFTP service onto the sub, hardcoded phone TFTP to the sub IP and it then registers to the sub but then 2nd choice is its default-gateway IP address.
It appears the 7921 will register to the CUCM that is set as its TFTP server.
It didn't matter what firmware was on the phone as the original image was 1.0.6
Any help here?
