ABSTRACT:
A method for connecting a telephone call for an extension coupled to a Public Switched Telephone Network (PSTN) to a handset coupled to a packet switched network is provided. Log-in information for the handset coupled to the packet switched network is received. An active handset for the extension is then deactivated in response to receiving the log-in information if there is an active handset. The method activates the handset using the log-in information. When a telephone call for the extension is received, a network address associated with the handset is determined. The telephone call is connected through the packet switched network to the handset coupled to the packet switched network at the network address.
