Good to know

  • Multiple SIP accounts or identities are not supported. The first identity is being used when logging in.
  • Phone credentials are stored on the Acrobits server to enable push notifications and save battery life.
  • Multiple SIP domains should be possible, but are not tested yet. We use one app per SIP domain.
  • We use OPUS as audio codec from the app to the Compass server. Compass transforms this codec to another codec if parties don’t support this codec.
  • Acrobits documentation can be found here: and
  • Android and iPhone behave differently regarding network settings. Please see the section Making a New App > Phone Settings
  • (Android) Issue found by Cloudsoftphone: When setting network constraint to Mobile data only, android is still using SDP over wifi. As of writing (28-10-2018) this hasn’t been resolved yet. Please contact Cloudsoftphone to get the recent status about this issue.
  • (Android) Issue found by IPerity: (Android) When setting network constraint to Mobile data only and when wifi is connected the account won't register. After wifi is enabled it’s registered again.
  • (Android) There seems to be another bug on Android where the pressed keys are not cleared. Expectation is that this will be fixed soon.


Getting our app template

Below you will find the steps to configure the Cloud Softphone following the configuration we made. But you can also get an copy of our app (which has the same settings). This saves you some time editing, and you have the confidence you get the exact same settings of the app as tested by us. To do this:

  1. Create an account on
  2. Send an email to stating your reseller/distributor and SIP Domain. And your account email address from Cloud Sofphone.
  3. We will create a copy with the correct SIP domain and ask Cloud Softphone support to transfer the copy to your account.
  4. You edit the design (see section further down below)
  5. You pay and push it to live.
  6. Read below (Section: Logging in into the Softphone app) how to login.

Login to cloud softphone. Make a duplicate on the dashboard from Cloud Id:
COMPASSSOFTPHONEPREVIEW. Edit provisioning options > domain and fill in the partner SIP domain. Save and go back to the app. Put in the comments that you want to transfer this app to our partner and mention the account email address.

Making a new app

The first screen asks for a feature set. Choose the Full-Featured app. All other (higher) feature sets should also work, but we didn’t test it yet.
After selecting a feature set, we need to select the features we want.


Selecting the right features

Below you will find the features we selected in our (working) app. It’s important to note, that some other features can be enabled and used in conjunctions with Compass, but we didn’t test it ourselves. The configurator shows the exact total one-time price, monthly price and price per user for the chosen features. These cost must be paid by the account holder and cannot be paid as an in app subscription.

Phone settings

The app has hundreds of settings, the vast majority never touched by end users. Pretty much every preference is configurable, but only the common ones are in the portal. (So most of these settings are not visible and not configurable in the Cloud Softphone portal).
Preferences are also not provisionable (by external provisioning feature). If you want one changed from the default, you would need to contact Cloud Softphone. See also for the settings that can be provisioned.
Advanced account settings can be provisioned via external provisioning (a feature that must be enabled). Or can be enabled manually by Cloud Softphone (if you don’t have the feature enabled). See the provionable settings here: Below settings are advisable to have set and we did this for our app template.

Non standard settings on iOS
Network constraint: Mobile Data
Network priorities for RTP: Prefer Mobile Data
Network Change Strategy: If Needed.
Start video automatically: off 
Visibility: HIDE

Non standard settings on Android
Network constraint: Any Network
Network priorities for RTP: Prefer Mobile Data
Network Change Strategy: If Needed.
Start video automatically: off.

The reason we set the app mobile data only as much as possible, is that we are not dependent anymore on the WiFi network configuration which might block VoIP or is unstable.
The reason the settings between iOS and Android are different is because when an android device is set to use mobile data only and is connected with wifi the registration will not come through. (Issue/Bug)

Logging in into the Softphone app

Please make sure your user has downloaded the app from the iOS or Android play store. The links can be found in the Cloud Softphone portal main dashboard.

  1. Create a new phone in Compass (Manage > Phones > Add phone). Choose ‘Compass Softphone’ as type and use a random name.
  2. If created successfully and if QR codes are enabled for your Compass company, you can open the phone and a QR code is displayed.
  3.  Provide this QR code to your user. (WARNING: This code contains the password of your SIP account)
  4. The user can scan the code with the Softphone App (Not with another QR code scanner).
  5. After scanning, two things happen: the app will be set up with the correct settings. And the app will be logged in, into this phone.

Log in manually:

  2. Tap on sign in.

As you may have noticed, Android has some more control toggles available than iOS. Due to the nature of this operating system Cloudsoftphone advices to leave this on.
