    I tried several SIP clients before coming across this one and to be honest I was ready to give up. The native client simply would not answer a call on 3g and on WiFi it answered but the other end kept getting a ringing tone. This app worked perfectly as soon as I had it installed both on 3g and WiFi. Happy to pay for the extra featured because guess what ... They work really well too! Definitel
