I am looking to see what system would be better in a tenanting situation. An office rents out offices for several other companies. The reception needs to answer with the correct company greeting and transfer the calls to the appropriate company. We would also like the voicemail to be tenanted to not allow people to here the other companies employees in the directory. I have already spoken with Mitel engineering and gotten some feedback from them but would like someone that has done this sort of thing before.
