Avaya 1220 MAC address issue
« on: December 09, 2013, 08:37:26 AM »
Hi. We are using DHCP to serve IPs to our IP phones. Recently we have started facing an issue, where some phones while booting up display 'DHCP server unreachable'. Further investigations revealed that the MAC address that the DHCP server was receiving from the IP Phones was different to the one mentioned on it. Our DHCP server is filtered and this was causing issues. Is there a reason why a MAC address would change?

Thanks.

Hi Michael, these phones were working properly before and recently we have faced this issue. I'll have to check if these are refurbished.

Thanks.

Hi eby83,

Do you know who owns the other MAC address as that might help you troubleshoot the problem?

Hi flintstone

No we don't know who owns the other MAC address.
