As far as I can tell, if you change the volume while on a voice announced call, when you hang up, the background music volume is changed to be the same as the voice announce call. I don't know why, but the user can't just adjust volume from here, they have to press the intercom key, make the volume adjustment and hang up. Until the next v.a. call.

Volume for anything on the speaker is the same (except ringing), unless I'm missing something. Sound correct?

Thanks.
