Dear All,
we are planning to purchase Cisco ISR 4451-x router to my company to do as VOIP router. Can anyone pls help this ISR 4451-X will support maximum how many NAT session simultaneously. I think it will support 5 Lakh nat session at a time. Please someone help and if possible pls share the cisco document link for this.
Thanks a lot.

You don't normally run into a "session" limit on the 4451, but a bandwidth issue. If you buy the unit with a 1Gb/s bandwidth licence, then you can fill up to that much bandwidth with as many sessions as you want.
Most likely, it will support many tens of thousands of NAT sessions at once.
