Question about Nortel 1140E
Our IP phones lose connection and does re-connect to the Sig. server. They will go through the retry and then says DHCP server unreachable. We have separate subnets and VLANs for the IP phones. We are doing Full DHCP, 802.1Q. We have verified everything on the network switches, power, Portfast, available IP address on the DHCP server, lease times are set for 3 months on that subnet,
, a manual reboot has to be performed before the phones come back on-line. It doesn't happen everyday but occasionally. The last time is happen over 100 phones had the issue. We are suspecting there an issue with the DHCP server but not sure... any suggestions
