We use an outside company for conferencing services that we reach via an 800 #. We are now going to be using a new conferencing company. Is it possible for me to program all my PBXs so that when the old 800 # is called I can route it to the new 800 #? I know I can set up a DMI to add and delete but my first thought is, since we are not the owners of this 800# is it even possible? thank you.
