how to change IP address(s) of SIP DEct RFP

[Aussie Pete]

HI
We have acquired a demo system to do some development work on nursecall messaging
I can change the IP address in the 430 but i can not find where to change the IP address of the DECT Base stations (there are three in a cluster)
If I change the address of the OMM on the 400 it doesnt change it, i have had a look at the CFG file but it doesnt seem to provide the IP address's of the base station
any help would be appreciated and i am a 400 novice

All things being default the RFP will get an IP via DHCP, is the 400 providing DHCP? look in there and maybe reserve an address for it.

Thanks for the reply
I worked it out
I found OM Configurator and changed it through that
