Panasonic introduced several SIP Wireless Phones to the market last year, the KX-TGP500 and KX-TGP550 Phone. These phones are a very unique type of phones that bring SIP technology and Panasonic Wireless Technology together on one platform.
The latest in SIP Technology from Panasonic are the new Desktop KX-UT SIP Product line. The new models include the KX-UT113-B, KX-UT123-B, KX-UT133-B, KX-UT136-B.

 These new Panasonic SIP Phones can be used in the same way as any other type of SIP Phone such as Polycom Soundpoint IP Phones, or Aastra SIP Phones. They can work on any type of Hosted PBX or Pure IP Phone systems including Asterix based IP Phone Systems.

The new models of Panasonic SIP Phones can fit into any type of IP Phone System with ease. The KX-UT113 and KX-UT123 SIP Phones are identical model, with the difference being the UT123 has a 2 Port Switch in the back for sharing a cable run between the phone and the computer. These phones can be compared to the Polycom Sound Point IP 321 and IP331. The KX-UT133 Phone has an additional panel of programmable keys on the side of the phone, while the UT136 is nearly identical to the UT133. The UT133 has a 3 line display and the UT136 has a 6 line display.

All of these phones can be powered either by a POE switch, or by using a power adapter (KX-A239). You have the option to wall mount the phones with the KX-A433 Wall Mount Kit. These phones are surely to become a contender in the SIP Phone market due to the design and ease of use of the phone as well as its competitive pricing.
