Hello,
I have recently upgraded from 6 to 7 and I have a few phones that are stuck in DHCP discovery main version 05.02.01.07 I believe these were sitting off the network for a little while. I went into options and noticed that IPv4 DHCP was disabled not sure how you enable it? Then I noticed IPv6 DHCP was enabled and I was able to disable it. Then the phone rebooted and now it's stuck on a screen I have never seen.
Assert 222
LinkMaint_Resiliency
Assertion failed-25
the DHCP Options on the PBX are as follows
ID 3 router
6 DNS server
44 NetBios Name Server
125 Mitel
128 TFTP Server
129 Call Server
130 IP PHone Identifier
134 DSCP
Thanks,
