IMS VoLTE
The IP Multimedia Core Network Subsystem (IMS) is an architectural framework for delivering IP
multimedia services on a private network. IMS provides support for the delivery of multimedia
applications and voice service over IP transport. The IP transport is the key in that it allows IMS to
communicate over any network that supports IP.
IMS provides Voice over LTE (VoLTE) solution on a private network, that supports audio, video, and
conference calling between users. VoLTE calls use the standard Android dialer and contact
application.
Based on the customer's needs, it is possible to install and configure the following options:
• ClearTone - An optional feature enabled by the agency to notify the user that they are on a clear
call (non-secure). To enable this feature, contact your system administrator.
NOTICE: If your Organization must make calls in a secure (encrypted) environment, see
Public Safety Experience Applications on page 137
representative for details.
If the IMS option is implemented in your private network, your LEX device, if enabled, will support the
following features:
• IMS VoLTE:
- IMS VoLTE/ViLTE (video) Calls
- IMS ClearTone
- IMS Conference Call
- IMS Voice Mail
- IMS Supplementary Services
• IMS Messaging
• Emergency Calling - see
Additional PSX applications are available on your private system and LEX devices, see
Experience Applications on page
IMS is not supported in the Public mode. To verify IMS and multimedia communication options are
enabled on the device, contact your System Administrator.
IMPORTANT: If your LEX device does not have a public SIM card available then Messaging,
PTT Calls, and Secure VoIP are not available in the public network and only work in the private
network.
If you are unable to make a phone call with the LEX device, contact your system administrator.
