The KX-NT700 works with your existing telephone system, or operates natively on your business or broadband data network. The system includes a Three-Party Conference feature that lets you conference up to three units together, or conference one analog call into a two-party IP conference meeting.
The KX-TGP550 has all the features and benefits of the KX-TGP500 and adds a corded base unit with a large white backlit LCD and 5 hours Talk Time, 5 days Standby, plus a Hands-Free Speaker phone, Handset Call Button on the base unit, and one-touch call transfer with Busy Lamp Indication.
This Panasonic KX-UT136B was slightly used in the 888VoIP offices. This phone is essentially brand new and comes with all cables, accessories and the original packing materials.
