We are testing the Avaya one-x mobile sip 6.2 app on the Ipod Touch IOS 7. When I try to make a call, the speaker comes on and the app does not let me unselect it. I have looked through the docs for the Avaya app and found nothing that mentions turning the speaker off. I have also looked on Apple's website for info but it only happens when I use the Avaya app. Thanks.
