I am relatively new working with AVAYA partner...have a situation with a system with Processr 4.0 upgraded to 6.0, VM 5, two 308's. The cards are out of order. I have read, the VM should be on the right of the Porcessor...it is immediately left and the second 308 is on the right of the processor...it skips extensions 27-30 for some reason. When I change(swap) the position the VM with the 308 on the right side I get the extensions but then all the incoming calls want to go to ext. 28. i revers locations and it's back to normal
