Patent Images
1. A method comprising:
- communicating, by a device, with a cellular network operated by a first network operator;
sending, by the device to a packet switched network operated by a second network operator, via a cellular data connection of the cellular network, a request to register for telephony services of the packet switched network; and
if a wireless connection to a wireless access point of the packet switched network is available, sending, by the device to the packet switched network, via the wireless access point, a request to initiate voice-over-internet-packet (VoIP) communications via the wireless access point and the packet switched network.

15. A method comprising:
-
receiving, from a component of a cellular network operated by a first network operator, a telephony request comprising a first identifier associated with a device that initiated the telephony request, wherein the first identifier identifies the device to the first network operator; determining, by a packet switched network operated by a second network operator, that the first identifier maps to a second identifier that identifies the device to the second network operator; modifying the telephony request by replacing the first identifier with the second identifier in the request; and forwarding, by the packet switched network, the modified telephony request toward a destination of the telephony request. - View Dependent Claims (16, 17, 18, 19, 20)
