Push Notifications

One of the features our users were waiting in anticipation are Communicator GO push notifications.

CloudPBX 5 is now running Push Notifications Service that will forward requests to our hosted Push Notifications Platform. Once push request is forwarded from CloudPBX, the platform will propagate push notifications to devices using Communicator GO.

This feature is adding more convenience to users connectivity when they are on a business trip, working from home or simply need to answer business calls when they are outside the office.

With push notifications, mobile app does not have to be registered via SIP all the time in order to receive incoming calls or notifications. This will make sure your Communicator GO will not lose connectivity when app runs in the background and it will save battery life of your mobile device, improving overall user experience.

Although users should only benefit from the way push notifications affect the app we have still left to users to decide whether they would like to use push notifications or not.

In case you would like to disable Push Notifications click Menu icon in Communicator contacts window and when slider opens click Settings. Once you are in Settings menu, click General and once in the menu remove checkmark from Enable push notifications checkbox.

On Android, push notifications are stopped when you use Quit option to terminate the app. Also, push notifications are stopped if you click on FORCE STOP button on your device (Settings -> Apps ->Communicator GO).

NOTE: Because of the way push notifications work, Communicator GO will not be registered once app goes to the background and as such, it might not be displayed as Online in CloudPBX Monitor page.

Automatic Updates

Communicator GO 5 also brings up a new update mechanism. In previous versions users would have to manually check App or Play store to see if new version is available. This is no longer the case as Communicator GO will notify users once new version is available for download.

Logging in

Communicator GO requires email address and password for login. Additionally, server address may be needed if cannot be resolved through DNS record based on the email address.

In case you have your own DNS server, by adding DNS SRV record for your e-mail domain, mobile and desktop clients will make Communicator GO login much easier for end users as they will only have to provide their e-mail address and User password associated with their CloudPBX extension and click Log In.

If you are unable to set DNS SRV or if DNS resolution fails you will receive notification DNS resolution failed and users will have to click ADVANCED and enter CloudPBX IP address when logging in with their Communicator GO client.

DNS SRV record that needs to be configured to point to CloudPBX is: _pwproxy._tcp.domain. 86400 IN SRV 0 5 10005 pbxserver.domain.

For more information on DNS SRV please check wikipedia link:

NOTE: In order for this feature to work, all e-mail addresses used must use your company domain (i.e.

  • Email: Enter email address associated with your extension. This is used as username for Communicator GO login.
  • Password: To authenticate Communicator GO with your CloudPBX server you will also need to provide user password generated on your extension.
  • ADVANCED: This button will display additional entry field named Login Server Address that will allow you to enter the address of CloudPBX you would like to register to. This is necessary in scenarios where DNS SRV record is not available and CloudPBX address cannot be resolved automatically.
  • Login Server Address: This field is shown only if ADVANCED button is pressed, and allows you to enter the address of CloudPBX you would like to register to. In case DNS SRV record is set up (as previously explained) this field does not have to be populated.
  • SCAN QR CODE: This button opens a camera preview for QR code scanning.
  • FORGOT PASSWORD: By clicking this button you will open a confirmation dialog for password resetting. Email and optionally server address fields need to be filled out before attempting password reset.

Logging in using QR code

It is possible to login in Communicator GO using specially created QR code. This is often used and helpful when you log in with Communicator GO for the first time.

When administrator creates your extension, you will be assigned a long, automatically generated user password on your email and typing it into Communicator GO can be error prone. With this feature you can simply scan the QR code attached in the extensions credentials email, by pressing SCAN QR CODE button and pointing your phone camera to the monitor. Once QR code image is detected Communicator GO will fill out all the fields necessary for login.

NOTE: Before you are able to use this feature CloudPBX Administrator must make some settings changes on CloudPBX, otherwise Address (hostname) field will be empty and users will not be able to register their clients.

Login to your CloudPBX GUI and navigate to

Settings -> Servers/Tenants and edit Server/Master tenant

Click Show Advanced Options and once you do that, you will be able to see QR Code Server option. This field must be populated with servers IP address or domain name.

Once entered, save changes and QR Code login should be ready for use.

Setting new password after logging in for the first time

When you log in Communicator GO for the first time, you will be asked to change your password. You will have to enter new password and retype it in order to confirm it. In case you make a mistake so password entries do not match or in case password is not strong enough, NEXT button will stay disabled. Once your password match our strength criteria you will be able to log in.

Location and Phone settings

Clicking on country name opens screen with countries to choose from.

  • DETECT: DETECT button tries to detect your country automatically. This works if you have Location Services enabled in your system’s settings. Information about your country is needed if you need to use E.164 numbers format when dialing phone numbers from your phone book.
  • SIM NUMBER: This field contains your automatically detect SIM number. If number cannot be read from SIM card, this field will be empty and you will be able to type your number manually. SIM number is crucial for callback feature.
  • PHONE NUMBERS: This section contain numbers defined with your extension. You can add more numbers using ADD NEW NUMBER button and sort them by priority using the drag handle on the right of number and label. These numbers appear in a list of numbers associated with your extension when someone tries to call you from Communicator GO or desktop Communicator.


Default dialer screen is displayed onceCommunicator GO 5 is started.

Call button in dialer screen has three states depending on softphone registration status and connectivity status.

If softphone is not registered and button is yellow, calls still can be made if callback option is configured.

There are three states Communicator GO dialer can be in:

Green - Call can be made over SIP protocol (WiFi and Mobile Data Networks)

Yellow - Call can be made with Callback module (Mobile Data Networks)

Gray - Call can not be made (No Network Connections)


In Communicator GO, calls can be made over SIP protocol, which is a primary option or using Callback module in pwproxy.

Call scenarios may vary and will depend on network connection (WiFi, Mobile Data, No Connection), service availability and connections (SIP Server, Callback Module) and setup in settings for “SIP over mobile internet”

If we for example take an first scenario for WiFi where order is:

  1. SIP Call
  2. Callback Call
  3. No Success

This means that in scenario where device is connected through the WiFi, app is connected to the SIP Server and Callback Module is available on CloudPBX, Communicator GO will first try to make a SIP Call, if unsuccessful, it will then try to make a call using Callback and if this fails it will display the message that call was not made.


You can add other users and contacts from phone book to favorites to have them in one place and have them show up first while performing an action, e.g. transferring a call.

Users can be added/removed from favorites by clicking Add to favorites or Remove from favorites on user’s details screen as shown in the pictures below.

  • Add Contact to Favorites
  • Remove Contact from Favorites
  • Favorites screen

Contacts from phone book can also be added or removed from your favorites by clicking on it and choosing Add to favorites or Remove from favorites.

Favorites screen appears when user clicks Favorites Tab from Header Bar in Phone Screen.

When this screen is shown, if there is no favorites, “No Favorites” label should be displayed in the middle of the screen. By default, favorites are displayed in Grid mode and sorted by name in ascendingorder.

Clicking on the favorite that is a Communicator GO contact (extension) will display extension options screen and if favorite contact is a contact from your device’s phonebook Contact’s Screen will be shown.


This screens will be displayed when user press Recents Tab from Header Bar in Phone Screen and list of the recent calls will be displayed.
