This is not something I would do, but it's still an interesting read.

What about a specific pattern of "buzzes" on the doorbell which unlocks the door?Mike said:If all you do is ring the phone, it's almost as bad as hooking it directly to the doorbell...
I reread this: We are talking about the entryway into an apartment building, not a traditional residence right? If thats the case I guess it is not so bad. I'm sure the other tenants would love to know about this (so they can use it).WayneW said:security by obscurity folks... if nobody knows he has this feature, then it doesn't hurt anything as the door is only unlocked for a short time. so unless somebody happens to be trying to open the apt building door while his phone rings by coincidence, nothing happens. And since it is a VOIP number, it is very hard to tie that to a physical address anyway. So unless somebody got his cell phone, it would be very hard to determine that phone number he used.
