Looking for a doorbell intercom solution

[sincityharley]

I have read through all the ways in which you can use LMCE. The one most interesting was being able to have a guest ring a doorbell and LMCE letting you converse with them via your cell phone. I haven't been able to find any solutions that would incorporate LMCE. Can anyone tell me what products are available to me so that I could set this up at home? Thanks
