We have an ESI-1000 with over 100 IP phones. I need to be able to change the IP address that the phones receive, as they don't seem to use DHCP or anything else controllable to get their IPs. Our vendor gave me ESI-Address to change the IPs, but this seems to be for Remote IP phones, not local. Can anyone help me a change a local IP phone to an IP that I specify?

Thanks!

Local IP phone set up is done in function 31. The local phones don't need or get an IP address; they communicate with the IP PBX via the MAC address.

THe PBX is apparently what hands out IP address to each phone based on their MAC address. Each phone does get an IP address based on the first IVC card installed. It seems that they simply count up from there and continue on to the next subnet without regards for any other systems using the IP. Our phones are getting IP addresses that are conflicting with some of our servers, so I need to find a way to change the IP address on a specific phone. From Function 31, you can set the MAC address on each phone, but the IP information is greyed out. What I need to do is specify an IP address for each IP phone. Is there anyway to do that?

What type of router or DHCP server are they using? If they are running a good router/firewall as the DHCP server, you can force it to assign the IP address according to the MAC of the phone.

I believe it is under 821 or 822 that you need to set "External DHCP to YES".

sorry for some bad info there, I was thinking IP 1 phones. I would suggest changing the DHCP scope, treating the range of ip address' as static in your DHCP server (that may be your easiest solution)or changing the IVC card IP address. Function 821 and 822.

Thanks guys, I had no idea about this - guess our vendor doesn't know as much as they think they do...
