Setup manual / iOS / Zadarma for iOS


We have created our own Zadarma application for the iOS smartphones users.

Zadarma for iOS allows you to:

  • Receive and make calls via SIP or Zadarma cloud PBX;
  • Send free text messages between Zadarma network users;
  • Send and receive SMS messages;
  • Monitor account balance in real time;
  • Use your phonebook thanks to an automatic integration.

You can find the Zadarma app on iTunes.

Setting up the Zadarma app for iOS

1. In iTunes find and install the Zadarma app.

2. Launch the app and enter the following data:

User name: Your sip number (for example 111111) from your personal account

Password: Password: Your sip number password can be generated here.

Click "Sign in".

User name: PBX extension number (for example 1234-100) from your personal account

Password: You can generate a password in the "My PBX - Extension numbers" section of your personal account

Click "Sign in".

3. The app is registered and you can make calls.

4. You can change additional parameters in the "Settings". For example, you can select the required codecs.

5. You can select the Server Port and Transport in the "Settings - Accounts" section. For example, in Southeast Asia internet providers might block standard VoIP ports, in which case you can use port 5065.

6. CallerID settings

In the section “Settings - Settings - Current Caller ID” you can change your CallerID (a number which will be seen by the person you are calling). Click on the CallerID field and choose a confirmed number or a virtual number connected with the service. Then click Save in the top right corner.

7. Remember the external number for Caller ID

This feature is necessary if you have several virtual numbers and you need to call the client back using the number the client dialed. To avoid additional costs, the feature is only enabled if the CallerID and client’s number are from the same country.

8. Display NAME/number

This feature allows to display the name/number of the virtual number which is receiveing an incoming call when using CallKit. If caller’s number is saved in your contacts, the name will be displayed.

9. Call forwarding settings

In the section “Settings - Settings – Call forwarding” you can set conditional or unconditional call forwarding to another number. Choose Call forwarding section, enter a number and check “Call forwarding is active” box. Then choose a status:

  • Always – unconditional call forwarding – all call will be forwarded to the provided number.
  • Unavailable – conditional forwarding – if the internet connection is stable the call comes through the app, but if the internet is not sufficient it will be forwarded to the chosen number.

Then click Save in the top right corner.


If there is no audio notification when you receive an incoming call, modify iOS ringtone settings in the "Parameters" - "Sounds" - "Message signal" section.

When using internet connection from a mobile operator, you need to allow the Zadarma app access to celluar data. To do so go to the phone's "Settings", "Zadarma" and enable the "Celluar data".
