Promising Sip client – Acrobits Groundwire Review

Latest update rendered app useless. Pushed calls cannot be answered. Delayed actions when clicking on app tabs ( call to favorites etc). Huge step backwards. Good start but needs improvement because app will crash when one tries to answer a pushed call while listening tune in radio app in the background. VPN should be added in the near future. Besides all this app leads its competitors.
