Business IP phone · CMK12P
Two lines, and nothing more.
The phone you put where someone needs to pick up, without turning it into a full work tool. It provisions like the others, carries the same directory, and costs what a two-line phone costs.
- 2 lines
- HD voice
- EHS headset
- PoE
- Opus
- 6-way conference
- IPv6
- A screen, nothing to set
- A 132 × 64 backlit LCD and two BLF keys: the phone shows who is calling and who is free, with no menu to dig through.
- One socket on the wall
- Two 10/100 Mbit/s Ethernet ports, and power over the network cable. No power brick behind the desk.
- HD voice, both ways
- Handset and speaker in HD voice, on the G.722 and Opus codecs. Six-way conference, and an EHS port for a wireless headset.
- Encrypted and standard
- Configuration and calls encrypted with AES, SRTP and TLS. The phone speaks SIP: it will work on another platform too.
