Hello Painkiller
Why is this the not the right place?
Re your question, - we use SME as our primary router here and we use other instances as general file servers and mail servers. We don't mix PBX with any other functions. PBX server runs with SAIL and vanilla SME only. It should not, in our view, be mixed with other functionality/contribs, except perhaps for low volume calls or domestic use.
Kind Regards
