Note: so far eScoopFone is only available for iOS devices.
1. Setting up
First you need an account on AETA’s SIP server. In many cases that is provided to you by your organization or a partner. Otherwise please contact us to purchase one. The conditions are similar to a Premium SIP account (see the related page).
You can get the eScoopFone app for free from Apple App Store: the app’s page is here.
Once the app is installed, when you launch it you get an error message because the SIP registration fails:
Now you must enter the SIP account’s credentials into the app: go to “Settings” ( icon), “AoIP settings” sub-menu, and enter the SIP number and the password you have been provided. Tap “Update”, come back to the main screen and you’re done! The green “SIP” box shows that the app is registered on the server:
Alternative method: you might have been provided a settings file that includes the SIP credentials. In this case, you just have to “share” this file and “Copy to eScoopFone”. The app opens ready and registered on the SIP server.
2. Making a call
Method 1 : direct dialling
Now you can set up an audio link with any audio codec registered on AETA’s server. What you need is just its SIP number. Tap the keypad and enter this number.
Tap the geen phone icon: the app calls the remote party and the link is set, normally using the Opus coding (G722 or G711 in case the remote party doesn’t support Opus).
To stop the connection, just tap the red phone icon. Then tap the green phone to call again, etc.
Method 2 : using the directory
You will probably find it more convenient to use the “Profile” directory when it contains the list of contacts relevant for you (this directory can be easily shared/imported).
Tap the profile icon and you are shown the list of existing profiles. Tap the one you want and it is loaded in the app, with its name displayed on the screen.
Tap the green phone button and the session is started. To stop the connection, just tap the red phone icon. Then tap the green phone to call again, etc.
During the session
The left bargraph shows the audio level as received from the remote end, the right bargraph shows the signal sent to the remote end.
You can adjust the level of the sent signal (cursor over the right bargraph), and adjust the level of the output to the loudspeaker or headphone (cursor on the left bargraph). Note that the general system volume (side buttons on the iPhone) are still operative too!
The “balance” cursor under the bargraphs allow you to adjust the mix of the microphone and the received signal that you get at the output. Full left: listen to only the remote end, full right: listen only to the microphone (local feed back).
Tap the “mic” icon and this mutes the sent signal; tap the “headphone” icon and this mutes the received signal.
“GPI” and “GPO” : when connected with an AETA codec at the remote end, you can exchange digital information with it. Tap to activate a GPI button, and a corresponding state is transmitted to the remote end. Tap again to deactivate it. Conversely, the GPO indicators show the states as sent by the remote end. The labels of these GPI/GPO can be customized, see “advanced settings” further.
Switch on the “padlock” to get protected against undesired changes or actions on the app during the connection. Switch it off again to regain control.
3. Manage the directory
From the “Profile” menu you can:
Create a new profile: tap the + icon and enter the number and name for the profile. Optionally you can set a bit rate that will be imposed whenever the profile is loaded; otherwise just leave it “Default”, and this profile will just use the bit rate that is set as general default in the “AoIP settings”.
Edit an existing profile: tap the icon on the right side and make the desired changes.
Delete a profile: Swipe the profile left and confirm “Delete”.
Share: you can export the whole directory to several possible destinations, for instance attach it to an e-mail. A file named “esdirectory.xml” is created. Conversely, you can import such file into the application and instantly get the directory ready for use.
4. Advanced settings
Opus bit rate: here you can set the default bit rate used for Opus coding. This will by default apply to outgoing calls, except if loading a profile that forces another value.
STUN switch: usually provides a shorter path for the transmission. Rule of thumb : activate STUN; in case connections succeed but no audio is received, disable it and retry the call. Especially, if the NAT type is detected as “symmetric” (in Settings > SIP status sub menu), STUN should be preferrably disabled.
Registrar: “FR” may be used for (generally) a shorter transmission path from the Western part of Europe.
Expected network quality: this influences the receive buffer size; select for instance “Bad” if the network is assumed to be of poor quality, and the system will accept higher jitter. “Standard” fits most situations, so change this only knowingly.
Reset: set all parameters to default values. Note: the SIP account is not cleared however.
Export settings: a file settings.xml is exported, towards various possible destinations, e.g. as an e-mail attachment, etc. It includes all the settings of the application, including the SIP account credentials. Conversely, such file can be imported into eScoopFone for an instant setup of the app.
GPI/GPO labels: here you can customize the labels according to your application of these GPIO.
The Tx and Rx small bars give a global assessment of the transmission quality, respectively in the send and receive directions.
Tapping the icon you can get detailed statistics about the running session, or the last one when idle.
