<div dir="ltr"><div><div>The Cisco Voice products have come along way in the last few years and can do some pretty amazing things. I would think something as basic as DNS would be trivial for these products.<br><br></div>Perhaps the best practice to remove the DNS dependency is a bit dated. But how are we ever going to know how well it performs at large scale and under heavy load if everyone is adhering to the best practice? If the product officially supports it, and Cisco will support your solution, then I say use it.<br>
<br>On the flip side, this wouldn't be the first documented best practice item that has gone untouched for years, in which customers are going against the grain.<br><br></div><div><div style="margin-left:40px">E.g., In UCCX the default maximum number of executed steps is 1,000, and we are told to never touch this value. However, in my experience, this number is increased in production environments quite often, and thus the best practice is intentionally ignored.<br>
