What can cause the "voice module is not ready" message in the spa112? I keep getting that on multiple spa112's while provisioning them. We are provisioning via TFTP and upgrading the firmware to 1.2.1 as part of the config. I have 2 files being downloaded, a general config for every device then a mac specific one with the two phone numbers. What I am seeing is the two files are being downloaded but the 112 still shows the old firmware.
They often sit in this state for an hour or more before we reboot them. After multiple reboots they will finally grab the firmware but sometimes still stay in this state.
