Thanks to everyone--
I don't know how to cross connect--
looking at instruction manuals, I have learned how to change ringtone, etc, pressing Transfer and then a specific number, etc.
I don't know which system and voicemail I have,
and if I ask the owner, I am 99% certain, she has no idea. She counts on me to pull rabbits out of a hat with various office equipment here and usually after googling, I am successful.
But not this Time.
Thanks-I will keep searching--
