Hello Bill, Below is my account configuration. I am using tcp account for sip calling. Account 1: mEdtSipId.setText("sip:android1 at localhost"); mEdtSipRegistrar.setText("sip:localhost;transport=TCP"); mEdtSipProxy.setText("sip:54.209.153.193:5060;transport=TCP"); mEdtSipUserName.setText("android1"); mEdtSipPassword.setText("android1"); Account 2: mEdtSipId.setText("sip:android2 at localhost"); mEdtSipRegistrar.setText("sip:localhost;transport=TCP"); mEdtSipProxy.setText("sip:54.209.153.193:5060;transport=TCP"); mEdtSipUserName.setText("android2"); mEdtSipPassword.setText("android2"); > Hi Manoj, > > There's a problem with SIP routing in your call.
