Android Sip Client
From VoIP.ms Wiki
This is a guide for the native Android SIP Client that is included with Android 4.1.1. We cannot guarantee 100% compatibility with all future Android releases since settings may change. We recommend the use of a wifi connection with these features, instead of a 3G connection. You also could be billed for your data usage if used over 3G/EDGE.
Launching the Android SIP Client
To open the Android SIP Client begin by tapping on the Phone icon in your app drawer.
Navigate to the SIP account details screen
Bring up the Settings menu by tapping on the three dots.
On the Call Settings page, scroll down to the Accounts option and select it.
From the Internet calling (SIP) accounts screen, select: Add Account, near the bottom.
Configuring your account
Tap Save after you have entered the pictured information. You should now be ready to use our service with this configuration. Feel free to dial our free Echo Test: 4443, as a test call.
