Product information

Description

Telekom Sinus A12 is a desk analog/DECT telephone with a single wireless handset in black. It combines an easy-to-read 2" TFT display, speakerphone and an integrated answering machine. The cordless handset uses NiMH batteries for up to 20 hours talk time and about 200 hours standby. The phone supports a phonebook of up to 100 entries and offers typical indoor range of up to 50 m and outdoor range up to 300 m.

Advantages

The Telekom Sinus A12 provides cordless convenience with DECT connectivity and a compact 2" TFT display that shows caller information and menu options. Its built-in answering machine records messages when you cannot pick up, while the speakerphone enables hands-free conversations. Battery performance (NiMH) supports extended use between charges.

Suitable for

  • Home use on an analog landline
  • Small offices or reception desks requiring a single cordless handset
  • Users who need a basic phonebook (up to 100 contacts)
  • Situations where hands-free calling via speakerphone is helpful

When it may not be suitable

This model is intended for analog/DECT environments and provides a single handset; it is not suitable if you need multiple handsets or a VoIP/Internet telephony solution. Advanced business features such as DECT multi-base management or large corporate phonebooks are not available on this basic model.
