Abstract:
1. A method for selecting a data compression technique for data transfer through a network between a first Internet Protocol (IP) network phone and a second IP network phone, the method comprising: a call control server receiving, from the first IP network phone, a request to place a call to the second IP network phone; the call control server accessing a network database to retrieve information regarding a network topology of the network between the first IP network phone and the second IP network phone, wherein the information regarding the network topology comprises information that identifies a plurality of data transfer paths between the first IP network phone and the second IP network phone; the call control server identifying, from among the plurality of data transfer paths identified within the network database, a particular data transfer path between the first IP network phone and the second IP network phone; the call control server identifying multiple intermediary links in the particular data transfer path; the call control server identifying a respective maximum transfer speed for each of the multiple intermediary links and a slowest transfer speed of the respective maximum transfer speed for each of the multiple intermediary links; and the call control server selecting the data compression technique for data transfer through the network between the first IP network phone and the second IP network phone based on the slowest identified transfer speed of a link within the multiple intermediary links.
