I am looking to connect analog phones on different branches. If i purchase VG-224 , it have IOS, i can define dail pattern, it have some builtin DSP's.
Now a question is raised that why i opt for router at first place if every thing is cater by my voice gateway. Whats your experience as i have never implemented it. Can i do routing, QOS and other voice feature or it. Or put in another way what additional feature i will get if i purchase router.
