<div>We have used a lot of the GXP400x series.. In my option, they have a high failure rate... we've been testing the SPA8000s in our lab... my opinion is that the architecture, everything from the software to the metal chassis is superb to the grandstream. The SPA8000 has a fan built in for cooling and a 25 pin amphenol connector which makes connection to a 66block a breeze. We plan to use them as customer CPE as we further deploy our FTTx service offering...</div>

<div>I'm hoping that linksys will release a 24 port version to compete with Grandstream's offering there...</div>
