I miss that one pet bird we had growing up who was an imitater. Not really all that good of one, but she certainly made an effort.
There was a period there in my life, about a year and a half, where I really really dove into the Asterisk PBX and VoIP in general. I was using a speaker phone and making thousands of calls.
This gave the bird a lot of training data, and she started imitating all the various phone signals.
She also learned to associate this with me visually, so her phone signaling would only occur when I was in visual range.
