Is there an effective method to keep my home handset from ringing when registered with the office extension? Hmm.. For some time I have just registered a different extension and used a custom status, queues, et al to route the calls when "telecommuting". However, it would be better if I could control whether or not the phone is ringing.. because wifey is a light sleeper and all that.. mainly I would prefer the extension not ring.. or go mute. I was gently reminded when I heard it ring this morning.. a queue call for our support desk started ringing. DND didn't do the job.. calls routed to voicemail with no ring. I removed that extension from the handset.. may try other things later.
