the blocking on VoIP is the almost the same in Tradditional telephony. The resources are similar:
For example, if you have a PBX with 30 Trunk (Lines), the you have only 30 resusrces tha can be used for calls
In VoIP those resources are the Codecs that you will need to convert the analog to digital Voices. whe you try to acomplish a call num,ber 31, you will have a blocke call (either in PBS or in the gateway)11th April 2005 at 10:40 #19820nada walhaGuest

Erlang theory estimates the number of similtaneous conversations. It makes no difference what transmission system you use to carry those converstions. You need to determine for yourself what resources you need to carry those similtaneous conversations, whether it be seperate telephone lines, ISDN channels, fibre optic channels, microwave channels or VoIP packets.
