I have run into this issue now at two separate sites.
I have a user who has two phones, one at home and one at the office. Both are configured to recieve calls on the same DN. The issue is that this seems to have strange effects on BLF and Watch buttons. Either the user cannot see the status of other users, or the other users cannot see this user. Is there a supported way to configure one user with one extension on two phones, and sill have BLF and watch buttons work as they should? Or is this not possible? I assume the system is getting confused as to which phone it should be monitoring, but there must be a way around this.
Any input greatly appreciated.
