Hello,
I have a customer with a Mitel MiVoice 250 running 6.2 firmware.
They have an issue where when the power goes out (blackout) and the phone system reboots, the internal DHCP server fails to start.
all the IP phones turn on, but do not get any DHCP until i log into the system. I have to turn off the DHCP server, and then enable it.
Then all the phones boot up correctly.
If i reboot the system or do a shutdown, when i turn it back on the DHCP works.
Any body have any ideas on why it fails after the power loss?
