Unless the seller confirms firmware pre-installed is 8.5 or higher, the SIP features will not work seamlessly. Phone comes with standard SCCP (cisco proprietary) settings and TFTP upgrade to higher firmware is cumbersome and requires high technical knowledge. Avoid this phone if you plan a hosted or cloud based SIP trunking feature for your business. Beware of sellers who will pawn you old stock phones from their unsold inventory. Ensure phone manufacture dates are May 2012 or later. Good Luck.

Couldn't connect to our usual, WPA-encrypted wireless network
A bit bigger and heavier than the UTStarcom F1000, the blue backlit ZyXEL P2000W V2 scores points for its normal-sounding ringtones. It's a bit thinner than the F1000, so it's a better fit for your pocket despite the added length. Unfortunately, that's pretty much it for the pluses.
