Has anyone heard or performed phone firmware upgrade on a CM and the system went down? or my question is can a IP phones firmware upgrade render the system to be down?
Hello all,
one of my sites have a g450 with a T1 going in and configured for failover instead of s8300. currently only three phones are configured to work in case WAN goes out. How and where do l configure the remaining phones to work when WAN goes down.
i appreciate you all

a vendor installed a DCP board on g700. this was due to calls fading out during calls. there is a RED alarm on the card how do we get rid of this alarm? is upgrading the firmware help. Any suggestions?
Thanks
