[phone-app] if hang up second call, first call should be active not paused

[Bill Filler]

build 212, Nexus 4

If you are on 2 calls, with one active and one on hold. When the active call is hung up, the call that was on hold should become active. Currently, it is paused and the user has to explicitly make it active by pressing the "play" button. On iOS the background call automatically becomes active when the foreground call is disconnected.

this is still relevant on Utopic build 157
We need to unpause the held call automatically when disconnecting the other call

[Gustavo Pichorim Boiko (boiko)]

I'm not sure I agree with this. The last time I tested this on other platforms the behavior was exactly the same as the one we have: after hanging up an active call, the second call stays held.

I can think of at least one use case where not switching the second call to active might be a good idea: if you are on a call with someone and this call drops while you are speaking, you might end up speaking to the person in the second call accidentally.

Marking as "won't fix" because the current behaviour is intended. If a user is on a phone call while an other call is on hold and the active call disconnects for any reason, user will have to activate the held call manually.
We can not know if the active call was hung up by accident or not. If user is in the middle of a private conversation and does not realise the active call has ended, he might simply continue talking without realizing again that someone else is listening now. The manual re-activation of the held call gives users more control over the whole experience.
