We have two offices that are connected via a Private Line T1. When we call people in other offices, we dial their direct extension (extension in both offices are in different ranges...200's and 700's). One office is Merlin Magix while the other is a Merlin Legend. Now to the question.....we can transfer calls directly to voice mail within each office, but when we try it between the offices, it doesn't work. It's like making a regular call to the other office. Is there a way, or an different feature code other than #56, that would allow this to work.

I'm not sure if I'm providing enough information. If not, let me know.
