TPx Support Center
Advanced Features in Call Control Menu
Shared Call Appearance allows administrators to assign up to 35 additional devices or lines to your account. These shared appearance locations ring on incoming calls just like your primary phone.
Physical Location allows proper support of emergency calling in countries and regions where your location cannot be derived from your phone number. If the Physical Location service is configured for you, you can only make calls from the physical location designated for the calling device.
Hoteling allows users to share phones on an as-needed basis (for instance, in a visitor’s office). As a Hoteling Guest, you associate your service profile with a Hoteling Host user. This enables you to use the host’s phone with your own service profile.
Push to Talk (Intercom) allows people to call each other and have the call answered automatically. You can control which users are allowed to call you in this way.
Charge Number allows an administrator to assign a charge number to the calls you originate; this is for the purposes of billing and record keeping.
