IP phone CMK12W — The extra desk phone, no network socket needed.
A desk added at the end of the corridor, a branch rented for six months, a counter moved: there is one thing left to find, power. The network runs over the company Wi-Fi, at 2.4 or 5 GHz.

- 2 lines
- Wi-Fi 2.4 and 5 GHz
- HD voice
- EHS headset
- PoE
- Opus codec
- IPv6
Advantages
Four reasons to choose this model.
What this phone does well. The other models in the range cover the rest.
A screen, nothing to set
A backlit 132 × 64 LCD and two DSS/BLF keys: the phone shows who is calling and who is free, with no menu to dig through. Three-angle stand, or wall mount.
Where there is no network socket
Built-in Wi-Fi on both bands, 2.4 and 5 GHz. The two 10/100 Mbit/s Ethernet ports are still there if a socket arrives one day.
HD voice on both ends
Handset and speaker both run HD voice, on the G.722 and Opus codecs. Six-way conference, and an EHS port for a wireless headset.
Encrypted, and compatible
Configuration and calls encrypted with AES, SRTP and TLS. The phone speaks SIP: it works on our platform and will work on another.

Compare with the other sixOn three devices
The desk phone, the browser and your pocket.
One number, three places to answer. All three share the same account, the same call log and the same customer record.
On the desk: the CMK12W
It rings, you answer. The BLF keys show who is free, and you transfer without putting the handset down.
In the browser: the softphone
One tab, nothing to install. The customer record opens with the call, and the note lands in the right folder.
See the consoleIn your pocket: the app
The same number rings on the phone. The call log fills up in one place, whichever device answered.
