Abstract:
An Internet Protocol (IP) telephony system comprises a radio communications interface and a processor. The processor is configured to execute a Communications over Internet Protocol (CoIP) application for an Internet Protocol (IP) telecommunication service; obtain an indication of a change of a Subscriber Identity Module (SIM) card of the mobile telephony device; and upon obtaining the indication of change, and generate, for sending over the radio communications interface, a registration message to the IP telecommunication service, the registration message including a new International Mobile Subscriber Identity (IMSI) for the mobile telephony device.
Abstract:
A method of operating an internet-based telephony system comprises establishing a communication between a first telephony device and a second telephony device through the internet-based telephony system. The communication at least initially comprises a first leg of the communication and a second leg of the communication, with the first leg of the communication existing between the first telephony device and the internet-based telephony system and the second leg of the communication existing between the second telephony device and the internet-based telephony system. The method further comprises receiving a connection-request message from the first telephony device; and, as a result thereof at least partially replacing a replaceable leg with a replacement leg having a different channel type than the replaceable leg. The replaceable leg is one of the first leg of the communication and the second leg of the communication, and the different channel type is either a data channel or a circuit channel.
Abstract:
A method for responding to a push notification after a missed call between a calling party and a called party's mobile device is disclosed. The method includes sending a push notification request directed to the called party's mobile device indicative of a communication. The method then detects that the communication request has failed and enables a dial-back operation to the calling party.
