Interop server enables WiFi calling for Nemont's Apple iOS users

Nemont Telephone Cooperative, a facilities-based telecommunications service provider serving parts of Montana, North Dakota, and Wyoming, has selected Interop Technologiesâ„¢ to assist them with device validation for their subscribers´ using Apple® iOS devices, the company said.

The Entitlement Layer Protocol created by Apple is a proprietary procedure required by each individual operator to support WiFi Calling on iOS devices. WiFi Calling assists operators in strengthening their network coverage and service offerings, while also combatting Over-the-Top (OTT) voice applications. For subscribers, WiFi Calling allows them to use available WiFi networks to make voice calls while in poor coverage areas and reduces their roaming charges during international travel.

Interop´s cloud-based Entitlement Server seamlessly integrates into any operators´ existing infrastructure and quickly facilitates Apple´s requirements by bundling the device enablement and collection of federally mandated emergency contact information (E-911) into one solution. E-911 facilitates the automatic association of a mobile subscribers location to accurately dispatch response teams to the correct location during an emergency. The operator retains individual control over enabling the WiFi Calling feature for their subscribers.
