Digital telephones, also commonly referred to as IP phones or VoIP phones, are devices that enable digital communication over the internet. These phones use digital technology to convert voice signals into data that can be transmitted over a network and back to a receiver in the same format. Some synonyms for digital telephones include internet telephones, network phones, web phones, SIP phones, and cloud phones. These phones offer advantages over traditional analog phones as they provide better call quality, enhanced features such as call recording and conferencing, and more significant flexibility in terms of scalability and integration with other digital communication systems.
