Android Native VoIP Client

Some Android devices have a built-in VoIP Client. VoIP works well with this VoIP client, but you need to make a small adjustment in the settings of your VoIP account.

Note: some manufacturers like Samsung have disabled the SIP capabilities in their custom ROM.

Setting up the Android SIP client

On your phone, go to:

• Menu
• Settings
• Call settings
• Accounts
• and click on "Add Account"

In the Android SIP client, enter the following details:

• Username (Account ID)
• Password
• Server

Next, you can indicate whether the VoIP account is your primary account. This is the "main" account among the SIP accounts and the account you will use by default for outgoing calls.

Now, you can specify whether you want to receive incoming VoIP calls. This consumes approximately 5% of your battery power over 16 hours of use.

Outgoing call settings

Finally, you can determine your "outgoing call settings." These can be found under:

• Menu
• Settings
• Call settings
• Use Internet calling

Then you can choose from:

• All calls
• Only Internet calls
• Ask for each call.

If you have a "standard" Android phone, "Ask for each call" is a good option. When you have a WiFi/4G/5G connection and want to make a call, the device will ask whether you wish to use your mobile or your VoIP account.
