摘要
A method of operating an internet-based telephony system comprises (1) determining that a telephony device associated with a customer of the internet-based telephony system has access to service of the internet-based telephony system; (2) sending a first location update signal to a public land mobile network associated with the customer; (3) receiving an indication that the public land mobile network associated with the customer no longer considers the internet-based telephony system as being the network visited by the telephony device associated with the customer; (4) determining the telephony device associated with the customer and the internet-based telephony system are in data communication, and (5) sending a second location update signal to the public land mobile network associated with the customer to register again the internet-based telephony system as the network visited by the telephony device associated with the customer.
