I had an Alcatel One Touch Easy and One Touch Max. Both had high chirpy tones and powerful speakers.
My budgerigar have learnt that I always responded to SMS tone of the phones and started to mimic them when she wanted some time with me. She did them with pinpoint accuracy so, it was impossible to tell whether it was the phone or her.
She also chirped parts of the ringtones for fun. Also we had a tune between us. I'd whistle a specific tune and she'd respond back with the same tune (or vice versa). It was a kind of pinging each other.
