I want to share the asterisk capability with the number of calls i pass through to give a better analysis about asterisk. is there is any existing module in asterisk or any body is writing the same module which can perform this. For Eg., P4 Machine 64 MB RAM zaptel/rip routing/iax routing etc ., Simultaneous calls -- 1000 - without bridging Simultaneous calls -- 100 - with bridging like that. Kannaiyan
