Windows phone 8 pjsip audio routes to speaker phone instead of earpiece always

Question

Ive build the sample pjsip library for windows phone and successfully registered and made a call.

butproblem is audio is always on speaker phone,not on earpiece ,

can anyone help to make the earpiece the default audio route always ?

Thanks

Answer 1

Access to audio routes is only allowed when a "Windows Voip Call" is active. This is achieved by calling the NotifyCallActive method on the VoipPhoneCall object. The VoipPhoneCall object is returned via a call to the RequestNewOutgoingCall method of the VoipCallCoordinator class. I've tried integrating PJSIP into the Windows Phone 8 voip framework but PJSIP is not able to run in the background process. Still trying to figure that one out.

Answer 2

You can't with the PJSip sample. If you search in pjmedia_audiodev you'll discover a TODO tag. Also, the sample does not manage VoIP calls, therefore you can route to the earpiece.

I hope this helps.
