here is what I am trying to do: I currently have 1.0.5 running on our primary box. Got 40 phones. HEAD is running on 2ndary box. Instead of reprogramming 40 phones to use 2ndary box, I want to install HEAD side-by-side with STABLE. I need them both on same machine so that I can halt stable, run HEAD and if HEAD crashes or something goes wrong, I can stop HEAD and start STABLE with little loss in downtime. Can anyone confirm that setting INSTALL_PREFIX in the Makefile truly seperates everything? My stable is using default paths but I will add a prefix of /usr/local/asterisk-cvs to the HEAD install. Just want to make sure before I compile HEAD and somehow put HEAD libraries where STABLE will read them. Thanks, Matthew
