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.

Abstract: A method for managing group subscriber numbers in a group messaging device reduces the required number of group subscriber numbers used by the messaging service. The required number of group subscriber numbers is equal to the total number of groups in which a user is permitted to be a member and not the total number of groups of users in the system.

Abstract: A management device is used in an access network including a plurality of data connections between end user devices and an aggregation transceiver device where the connections are aggregated for onward connection through the access network. The access network stores a plurality of different profiles, each of which specifies a set of values for a plurality of parameters associated with each data connection. The device applies one of the stored profiles to each connection, and receives a notification in the event of one of a predetermined set of notifiable events occurring on the connection. It is determined if more than a predetermined number of notifications are received within a predetermined period for a respective connection and, in the event of such a determination being made, a different one of the profiles is caused to be applied to the connection.
