kp_odata,
Check out the thread on the MP-108 here
http://www.3cx.com/forums/viewtopic.php?t=90
There are ini files for the 114 and the 118 posted there that work. I have 2 114s and 1 118 and have moved the ini files between them without issue. You will need to change the authentication info, IP's and the caller ID but other than that you should be OK.
Hope this helps.
Brian
