Dear people, I'm quite new to PJSIP, had a look at source code, and the website. Still I have a few (probably) simple questions: - If my pjmedia_aud_dev_info caps contains PJMEDIA_AUD_DEV_CAP_EC, does this always mean that Echo Cancellation is on? Point is that I still get echo, and I checked run-time that the caps contains PJMEDIA_AUD_DEV_CAP_EC. - My pjmedia_aud_dev_info's route, contina PJMEDIA_AUD_DEV_ROUTE_BLUETOOTH (as I see while in a call). How do I check if a Bluetooth headset is paired with my iPhone? And, if there is a Bluetooth headset, how do I select this audio route; and how back again to receiver/microphone (or wired headset)?
