Appearance overview
The handset is made of thick and durable plastic. It gives the phone elasticity and weight, the main cover of the phone is matt but there is a lot of prints around the display as always :). Compared to other phones, the handset is quite long and narrow in hand fits perfectly; when talking, it very conveniently runs along the face, the microphone is slightly below the level of the mouth. The buttons are rubber and do not protrude beyond the phone but are quite clearly felt due to soft rubber. To control the phone menu in the middle there is a joystick, it is not as convenient as buttons, but it quickly and accurately runs through the menu. In addition, there are 2 buttons at the top, the left one shows the last incoming calls and the right one allows you to choose one of 8 SIP accounts for an outgoing call, in my opinion it is very convenient to rarely see a phone in which you can select the desired account in two clicks.
Charging the tube (glass) is separate from the base, all glossy.
The base as well as the charging is glossy, from the back there is a mount on the wall and an entrance for an Ethernet and power supply. From the right, the indicator of the state of the base and the button to synchronize and search for the tube, the design of the base is at the highest level.

Web interface
As soon as I received the phone, my first wish was to go to the web interface and quickly connect it with the worker's Switchvox, I opened the manual in search of the IP address (not to accidentally put the whole grid), but I didn’t find anything there. I don’t find anything in the manual enclosed in the box about SIP, IP, WEB, on the website panasonic.ru, only
here I found a complete manual, well, in principle on
pbxware.ru I bought it.
The base received IP via DHCP, having tried to get into the WEB I realized that everything is not so simple, it turns out that the WEB is turned off by default and you can turn it on only from the handset, the IP Service / Built-in WEB menu and this turns it on for a while. The default for the WEB interface user: admin password: adminpass (the first time I see this password by default)
I am always in order to better understand the iron looking for screenshots of the menu or web interface, you can see in it everything that it can and even more.







And so from the pictures you can essentially understand everything that this phone can do, but I especially liked it:
- SIP can work on UDP and TCP
- G722 codec anywhere on DECT phone.
- Incoming calls can be distributed by handset, depending on the account CIP, for example, if you register 6 CIP numbers, they can define for incoming calls each one handset.
- You can allow up to 8 different SIP accounts per phone.
- Ability to organize groups for incoming calls. Each SIP account for an incoming call, you can bind more handsets, when they call, they will ring simultaneously
- For outgoing calls, you can also bind your unique CIP account to each handset, it is convenient when you need to pay bills to the CIP operator at the end of the month
- Call transfer with and without notification, at the phone menu level during the call
- Conference up to 3 phone level users
- Internal communication between the tubes, well, this is not news I think, but it's nice to see the list of "neighbors" in the menu of the tube
- A black / white screen with a color one obviously wouldn't stand for 12 hours of conversation, but I didn't feel the need for it
- The phone works 100% with Asterisk and Switchvox (the manufacturer stated this)
- Convenient additional buttons (Inbox / Missed and Line selection)
