METHOD AND SYSTEM CONTROL FOR THE SETUP OF AN IP TELEPHONY CONNECTION

摘要

The invention relates to a method and system control for the setup of an I P telephony connection between an original terminal and a destination terminal in an IP network over a gateway of a branch exchange. To increase the availability of the overall system for each IP terminal and to enhance in this way the voice quality of the IP-telephony connection, the setup of a connection between the original terminal and a first gateway is effected, according to the invention, by means of a list of IP addresses, a connection between t he first gateway and a second gateway is set up by a system control of the branch exchange, and a connection between the second gateway and the destination terminal is effected by the second gateway, the setup of the connection between the first gateway and the second gateway through the system control comprising t he determination of a gateway with spare traffic-handling capacities among the several gateways of the branch exchange and the definition of this gateway as being the second gateway.
