You can use this table to estimate the bandwidth required to support a given number of lines (voice paths) accross your broadband connection or for reverse calculations you can view how many lines your current bandwidth can support. Two compression algorithms are assumed (Codecs). For example, if you require 5 lines @ G.729a compression, you would need a minimum of 120kbps to support it. In reverse, if you have 320kbps bandwidth, you could support 4 lines at G.711 or 13 lines at G.729. This table is to be used for estimation only, as there could be many other factors uniqure to you, that are not taken into consideration.
