Zoiper IAX SIP VOIP Softphone APK

Among the best sip clients I have used, even though some of its goodies come at a price. Easy to setup but also highly customizable. Voice quality is the best so far (have tested over 15 clients, free and paid solutions). BT (plantronics) works fine. BT disconnects while on call if interrupted by incoming gsm call and needs to be restarted. No way of regaining audio focus. Phones: Samsung s5 mini lollipop and samsung s6 edge marshmallow. Here we provide Zoiper IAX SIP VOIP Softphone V 1.51 for Android 2.1++ *** THE BRAND NEW ZOIPER 2 IS NOW IN OPEN BETA *** get it here:
