The ability to record is giving by your supplier , usually the supplier don't allow it because it drop double load on the server
To let you record he have to give you 2 connections access , which mean you will consume double the normal bandwidth
Secondly each server can run up to 100 connection , if the supplier decide to give recording rights it would suffice for 45 clients instead of 90 normal client (10% is reserved for safety)
