Telephony: Enhancements for telephones

1A-telephony is one of the most popular 1A-options. Improvements to telephony and the devices themselves are very important to us.

Recently, we have released an update containing a number of firmware updates and configuration enhancements for all supported Tiptel and Yealink models.

  • Firmware v72 for Yealink T1x, T2X and T4X
  • Improvements to the update mechanism for firmwares older than v70
  • Automatic adjustment for daylight saving time
  • DND can now be toggled on and off with the button on the device
  • The line buttons are now automatically configured to use multiple phone lines

We have also added two new Yealink models: the T21P and T22P.

Yealink T21P
Yealink T21P

Yealink T22P
Yealink T22P

The T21P is an entry-level model with a 132×64 pixel LCD (5 line display). This unit has two line buttons, and supports OpenVPN. The T22P has a larger display and has three line buttons.
