I usually have my mobile in my pocket, on "buzz". If Mr T is sitting on my lap and it vibrates, he wont settle until Ive taken it from my pocket and "dealt with it" ....
When the landline rings he will go and sit next to the phone and miaow until I answer it.
When I answer it and start to talk, he settles himself down, purring, as he knows its a lap opportunity.
If he thinks I have been talking for too long, he puts his feet onto the phone - he has cut me off more than once .... I'm not sure if he knows what he is doing or it happend accidentally and he has caught on that he gets a pretty swift reaction from me!!
