- a distributed set of application service nodes deployed on top of the Internet and including a plurality of base stations;
- and
- a plurality of VoIP terminals, located on the Internet, accessing the overlay network, one of the plurality of VoIP terminals latching onto one of the plurality of base stations, the selected base station onto which the VoIP terminal is latched being the ‘portal base station’, the latched VoIP terminal communicating only through the ‘portal base station’, to converse with another one of the plurality of VoIP terminals and for accessing backend services, the ‘portal base station’ being the sole entry point and communication proxy for the VoIP terminal 20 vis-à-vis the overlay network.
A method for establishing connection between a voice over internet protocol (VOIP) terminal and an overlay network comprising:
- obtaining a list of SIP registrar pairs;
- selecting a first pair from the obtained list of SIP pairs;
