How do you set the extension the F1098 key dials into for VM? We just migrated from an old UCB system to the new NEC BCT system and the VM extension changed from 1000 to 6500. Previously we had a vendor set up all our phones to use F1098 to dial into VM. Since the change, those keys are not working. The current vendor tried setting up a soft key for VM, but it doesn't work on a lot of phones. They just want a list of phones with the key not working, but personally, I'd prefer to just get the F1098 command working again as it was previously.
