Configuring Zoiper - Mobile
NOTE: Please be aware that if used over 3G/4G/EDGE then depending on carrier and service plan used, you may be billed for your data usage.

Configuring Zoiper for use with Callcentric is pretty straightforward and can be completed in a relatively short time.

We recommend that you read each step through in its entirety before performing the action indicated in the step.
STEP 1 Launching Zoiper mobile
Open the Zoiper application by tapping on the softphone's icon on your mobile device interface. For this guide we use an Android based device:

After launching the application, please tap on the Config icon on the top right corner of the application, as indicated by the screenshot below. Then select the Accounts option.

From the Accounts screen, tap on the option Add Accounts...

... followed by the SIP option, to configure a new Callcentric account in the softphone:

STEP 2 Configuring your Callcentric account
We will now create a profile and enter the required credentials, such as your Callcentric number, password and SIP server:

Account name:callcentric
Username:This is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.
Password: Enter your SIP Password here. Your SIP password is the same password you create when you sign up for your Callcentric account. Optionally you may change it in your account preferences.

Your configuration should look similar to the one shown in the picture below:

STEP 3 Configuring extra settings
We will also configure basic codec settings. To do this please scroll down, and select the Codec Settings option. On the Codecs Settings page, ensure that only uLaw is selected and no other codecs are checked.

Tap on the Save button to continue.

Next, please select the Network Settings option, and set the option Use STUN to No.

Once you are done make sure to save your changes by clicking on the Save button. You will be dropped back to the account selection screen, where you should see that your profile is registered to your Callcentric account, as shown on the screenshot below.

If you encounter any errors please double check your credentials and make sure you have entered them correctly.

STEP 4 That's it! You can now make a phone call
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you can place a call to a traditional landline or mobile phone by dialing either:
1 + the area code and number for calls to the US
011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).

To test inbound calls from Callcentric to your Asterisk installation, follow the directions listed in this FAQ.
