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 More ..., Settings and in General menu toggle Push Notification slider to Off.

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 found by resolving 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 Login and enter CloudPBX IP address in order to log in 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.
  • Host(Domain): This field is shown only if Advanced Login 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.
  • Advanced Login: This button will display additional entry field named Host(Domain) 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.
  • QR Code Scan: This button opens a camera preview for QR code scanning.
  • Forgot Your 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.

  • SIM Card 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 once Communicator 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”

Table above displays the order in which Communicator GO will try to establish call in different scenarios.

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
  • Contact Added Favorites
  • Remove Contact from Favorites
  • Communicator GO Favorites list

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 the favorite which 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.


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

In case there is no recent calls, “No Recents” label should be displayed in the middle of the screen.

Recent calls are displayed in list mode and sorted descending by the date/time.

Clicking the favorite which 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.

When you press Communicator GO icon in the bottom bar list of Communicator users from your organization will be displayed. Users can be sorted according to presence and department in ascending and descending order.

Clicking on a user will open up user’s details screen from which you are able to see user information and perform different actions.

In case user associated additional phone numbers with their extension, these numbers will be listed as well and you will be able to dial them by simply pressing the number.

By default, "All" is selected for departments so all the users are available on the list, however, in case you need to filter users by specific department, you must click All to see a list of all available departments.

To filter users by specific department, click on preferred department in the list. Once department is selected you should only see Communicator users that are members of that department.

In case you would like to restore default view for all departments simply repeat the process and instead of specific department select All from the list.

SIP Call

SIP Call Screen appears when user initiate or receive a call through CloudPBX . With CallKit integration introduced in Communicator GO 5 iOS, options on connected call are similar to options available in native iOS dialer app.

Once call is connected Communicator GO allows you to perform several actions:

  • Mute: Mute allows you to disable the microphone on your device, preventing any unwanted communication on your side to be transmitted to other side of the call.
  • Hold: Hold option will put caller on hold and play Music on Hold until Hold is pressed again or call is transferred to another destination.
  • Speaker: Press Speaker button if you would like to put your device in speakerphone mode, allowing you to continue the without holding the device on your ear, or to allow other persons in the room to join the conversation through a single device.
  • Transfer: Transfer button allows you to initiate blind or attended transfer to CloudPBX extension or outbound number.
  • Audio: SIP Call Audio Settings Screen will appear if user taps Audio Settings Button from Call Bar in Call Screen on image 16.

Default values are taken from iOS Device’s values for output and input. Range of slider goes from 0.0 (mute) to 2.0 (gain is increased by 200% of the device’s gain).

  • Statistics: Statistics will display Call Statistics Screen with variety of statistics information like Call time, total of transferred packets, packet loss etc. for ongoing SIP Call.
  • Add User(s): Add User(s) option allows you to create dynamic conference by adding one or more people to ongoing call. With this option you can add CloudPBX extensions or any number available from your contact list.
  • Dialpad

Also, there is special case, when there is SIP Call in progress in Communicator GO app, if there is incoming call (GSM Call) for device (iPhone, iPad) in device’s default Phone application, that GSM Call take priority over SIP call. In this case, all SIP calls that are in progress are put on hold, until GSM Call interruption is ended.

This is default for all iOS devices. As it is stated in Apple’s official documentation on this link:

Providing Guidelines to the User

“There is no programmatic way to ensure that an audio session is never interrupted. The reason is that iOS always gives priority to the phone. iOS also gives high priority to certain alarms and alerts”

Call transfer

You can transfer a call by clicking transfer icon from call options menu. You will be presented with Transfer options.

Default option is blind transfer (toggle switch is set to Off) and if that is your preferred selection to do is to press To contacts... and select person from CloudPBX User list you would like to transfer call to. In addition, you can also transfer call to anybody on your Contacts list.

However, if you would like to make Attended transfer and would like to talk to the person you are transferring call to, you will press toggle switch in order to set it to On and then click To contacts... and select person you would like to transfer call to from Users or Contacts list.
