I use CSipSimple (free). It has every feature I need and works quite well. I was quite surprised to find that incoming SIP calls will wake up the phone, unlike my old Iphone. Good going, Android! 73 Kyle K0KN --- Original Message --- I know I've seen this before but I can't locate it after searching for nearly an hour. The question; which android sip client is "best" with app_rpt and can anyone advise on the setup required on the allstar server? Again, I apologize but I can't seem to locate the original post anywhere. 73 de K0JSC
