Abstract

A network device receives, via a user interface, a selection to call a contact's mobile device. The mobile device detects a feature, on the contact's mobile device, that supports presenting a priority call notification and initiates, via a first communication protocol, a pending call to the contact's mobile device. The mobile device presents, prior to the pending call being connected and based on the detecting the feature set, a user interface to solicit a priority indicator option. The mobile device receives, via the user interface, a selection of the priority indicator option and sends, via a second communication protocol, a priority indication flag for the pending call.
