Apps and the Application Button
You can use the Apps app to access special services on the phone.
You can use the Application button to start applications such as Push to Talk or other services on your
phone. The Application button is located on the left side of the phone.
Depending on how your administrator sets up the button, you may be able to use it from the main screen only,
or you may use it from any menu or service, or even when the phone is locked.
The button can also be configured to start an application immediately after you press it or only after you hold
it for several seconds.
For more information, contact your administrator.
Use the Push to Talk Application
You can use the Push to Talk service to communicate (similar to a two-way radio) with members of your
organization. Your administrator must set up the Push to Talk service, and then you must subscribe to the
service in the Self Care portal.
Your system administrator provides detailed information about how to use your Push to Talk service.Note
Push to Talk uses the same audio path as your phone ringer. If the audio path is for the phone to ring, when
you use Push to Talk and you plug in your headset, the audio moves to the headset.
