Softphone Settings

Phone Manager Mobile can become an extension off the telephone system using the built in SIP softphone. If a Phone Manager Softphone license has been assigned to the user then the Softphone can be enabled as and when required.

Enable Softphone

Enable to use the softphone.

Use CallKit (iOS only)

This setting is on by default (from version 10.1.391) and determines if the phone will use 'CallKit' functionality for ringing. It is recomeded to enable this setting.

If you change the Use CallKit setting, then Save the setting and then kill the App on your phone.

You must then clear your session on the AppSuite server before starting up the App again to ensure the new notification method required for this change takes effect.

Failure to do so may result in missing or duplicate notifications.

Run in background

This setting is on by default and determines if the phone will try and stay connected when the app is in the background.

Use echo suppression

This setting is on by default and enables the built in acoustic echo suppression of the phone.

As usual with echo suppression it may be necessary to reduce the 'Microphone gain' setting if the speaker volume is turned up high to avoid echo. Additional settings are available further down the settings page to alter the way echo cancellation works that may help in noisy environments.

Make sure that the noise canceller is enabled in iOS (in iOS settings General->Accessibility->Phone Noise Cancellation).

Use proximity

This setting is on by default and blanks the screen when it detects items in proximity. This avoids things like your ear pressing a button during the call.

On iOS this only controls proximity in the app, not the behavior of the native 'CallKit' function.

Phone vibrate

This setting is on by default and determines if the phone will vibrate when you get in app notifications (e.g. ringing or new chat).

Note it does not alter the behavior of OS notifications when the app is not running - these are controlled by the OS phone settings and therefore these can vibrate even when this setting is off.

Depending on the version of the OS, the volume level of the softphone ring and audio may be controlled by the media volume of the phone not by the ringtone volume

Use 256ms echo path

This setting is off by default which means a 128ms echo path will be used. Turning this on may improve echo cancellation but at the cost of a small increase in audio delay.(This setting is only effective if echo suppression is turned on.)

Use non linear processing

This setting is on by default. This setting will adjust echo cancellation. (This setting is only effective if echo suppression is turned on.)

Use full duplex

This setting is off by default. This setting will adjust echo cancellation. (This setting is only effective if echo suppression is turned on.)

Microphone gain

This setting determines how sensitive the microphone is. Increasing the sensitivity may improve how loud you sound to the caller, but increases the chance of getting echo from picking up the phone speaker and increasing background noise. A level of about 35 tends to suit most people in normal environments.

Endpoint

This is the extension that Phone Manager Mobile will register as with the telephone system. A list of your possible softphone devices will be shown here with a check mark against the one currently being used.

The list of extensions is generated from SIP devices assigned to the user's DEE user on the telephone system.

Failover Device

If you lose your data connection while on a softphone call the server can transfer the call back to you. The device select here will be the target of that transfer. The normal configuration for this is to transfer the call back to your primary extension, this will ensure the call follows your predefined routing and should find you again on whatever device you are on.

To disable this feature select '(None)' from the list.
