Yes, * could interface an existing PBX through some of it's extensions. 
I am doing that now with 3 extensions from our legacy PBX. The only 
'problem' is that someone on the legacy PBX must dial an extension (in 
our case x313, x397 or x404) and if it is busy dial another extension. 
It makes it harder for the user.
