No problem, go to the vm/aa tab and click on 'open block table'
click on 'menu' in the left hand column.
click on 'FWD STN' menu and enter the following into an empty row:
501 goto MBX 501
click on 'save & exit'

it sounds like its working already how you have set it up (same as a normal svm-i)

I am having problems all over the place as when i logged out and back in half my programming for the voicemail disappeared!!
looks to me that the software/hardware is not up to scratch yet and it may take a few months and the odd sw upgrade to steady it up.
