Abstract
A method and a system for providing firewall access to inbound calls in a Voice over Internet Protocol (VoIP) communication session. The server, after receiving a message for an incoming call, sends a PUSH alert notification to the destination device via a cellular network which lacks firewalls to stimulate creation of a new pin hole through the firewall by a renewed registration from the destination device of a Session Initiation Protocol (SIP) application.
