[OpenSIPS-Users] High Volume MediaProxy

[Muhammad Shahzad]

As i said each call consumes 4 ports at Minimum. Since we have Maximum port
number 65535 and subtracting Standard ports below number 1024, so max
possible available ports are around 64K which means in theory you can not
have more then 64K / 4 = 16K concurrent calls running on a single machine.

I did read somewhere there is some kernel variable which you can Change to
increase available ports but i never used it nor i have experience how it
will effect voip Services.
First Thing that effects is bandwidth, then NIC, then CPU and then RAM i
guess.

(Sorry i am testing Windows 8 right now and it really messes up the text i
am writing here. Apologies for inconvenience).

Thank you.
