If you are not familiar with AMO config using these following AMOs, then yes, you are probably going to struggle with this one:
AMO BFDAT - to build a Function Block to assign "SIP" to a STMI board
AMO BCSU - to build the STMI board, with the Function Block from AMO BFDAT
AMO CGWB - needed to assign IP Address, netmask, default gateway, CODEC info, etc.
AMO SBCSU - used to build the actual SIP phone(s)
AMO SDAT - needed to add the attributes MBCHL & (possibly) DMCALLWD
I can post some sample configurations over the weekend if you would like to give it a try.
This config is not difficult, but tedious if you are not familiar with the AMO process.
