Hi,
As Chelungas indicated, you only need to do the signalling and trunk config at both ends (CM & SM). If not aware already, SMGR is used to administer SM. You have choice of TCP and TLS protocols depending on your requirements. Pretty straightforward really, if routing patterns, dialplans, etc are not required at the moment.
Here's a link to a sample doc. Just ignore parts you don't need immediately:
