I have a hospital on a 1000M rls 6.Osw callpilot voicemail 5.0 I have a small physician office that we took over and like to move it onto the 1000M. What our my options for moving their trunk lines on my system. Their main number 734-542-1234 conflicts with my 734-591-1234 so I would think I am unable to port that number to my ATT PRIs. Is there any other thing I can do? Let me know your ideas as I want to do this with the least cost possible. Thanks
