Aastra SIP – DECT Solution


SIP-DECT – Wireless Voice Over IP Networks

Mobility is provided to the Voice over IP (VoIP) network through SIP-DECT using the following technologies:

  • VoIP – Voice is carried via an IP data network to an IP radio fixed part
  • DECT (Digital Enhanced Cordless Telecommunications) – Successfully tested technology for conveying voice securely through the air from the IP fixed part to the handset

Whether an organisation already has an existing data network, already uses wireless voice or is just looking to have a scalable, future-orientated solution for years to come, SIP-DECT is a recommended solution. Through using wireless voice and DECT together – SIP-DECT – users are able to enjoy the many advantages of IP networks working together. Aastra has developed radio fixed parts (RFP) with IP interfaces for integrating DECT over IP networks.
