1. No need to wire or change the current decoration. Stable reception and reliable performance. With the help of digital encoding and decoding technology, each system has its own unique code to ensure that there is no error between the calling systems
2. Two-way communication, but the ordinary business buzzer only establishes communication between the master station and the extended set. That is, the extension can communicate freely not only with the master station, but also with other extensions. The phone set as a terminal can be converted to a host for group calls, or it can be converted to an extension that receives signals from other extension terminals. It can be used for one-to-one calls and one-to-many communications.
3. It can be connected to wakie walkie talkie for voice calls
4. Function: interconnection between 99 devices, two-way communication, announcement or one-way conference, caller ID, call prompt tone, automatic call tone communication, backlit LCD screen, call intercom, etc.
