I have a query re routers and cisco phones. I am going to run @200 Cisco IP phones over a point-point wan link to a Cisco IPT system. My question is does the router need to have dsp chips to aid processing ? Thought these were only if you had e1 cards in the router ? Do they help with processing of voice packets just with IP phones directly connecting over the router or ar ethey simply not required and QoS and normal router processor will take care of it ?
Hopefully an easy one to answer !
