IP phone CMK20 — Three screens, everyone in sight.

The reception phone. A main screen for the current call, two screens for colleagues' keys: no more paper labels to re-stick when someone changes desks. A hundred and six keys and twenty SIP accounts.

Advantages

Four reasons to choose this model.

What this phone does well. The other models in the range cover the rest.

  1. Three screens, no paper labels

    A 4.3-inch main screen for the current call, two 3.5-inch screens for the keys. A colleague changes desks, the name changes on screen: nobody re-sticks anything.

  2. A hundred and six programmable keys

    The phone for large floors and reception desks that route every call in the building. Twenty SIP accounts, and every extension's status followed live.

  3. What it keeps from the day

    Two thousand contacts in the directory, two thousand more over XML or LDAP, call recording, the call log and call filtering.

  4. Encrypted, and compatible

    Configuration and calls encrypted with AES, SRTP and TLS. RJ9 or EHS headset, Plantronics wireless headset over Bluetooth. The phone speaks SIP: it works on our platform and will work on another.

On 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 CMK20

    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 console
  • In your pocket: the app

    The same number rings on the phone. The call log fills up in one place, whichever device answered.
