if u want some help with asterisk let me know, it failry simple to get work with ser, i dropped sems along time ago cause asterisk is better. Have voicemail and pbx, what u want to watch out for is how you are grouping callers etc, what I do is all users (corporates ) who need features of asterisk get an entry in grp table in ser, which says corporate, only these calls goto asterisk, the rest stay in ser, which saves overhead, cause asterisk does slow things down.
