I have it integrated with three different PMS systems ,That is part of the great support, Franks FOrte before Phone Suite was call Acct. Software,He will work with you on getting the most out of you interface to the extreme of working with the PMS originator ,if my memory serves it has 4 parameters to choose ,Hobis1 Etc. The smaller 64 does not check in ,Check out through PMS you simply press a one touch button on console the 110 does, you can either use the costing provided by Phone Suite or the PMS system,I have found it is generally less expensive to use the phone Suite versus the PMS ,
