Cordless Advanced Technology—internet and quality (CAT-iq) is a technology initiative from the Digital Enhanced Cordless Telecommunications (DECT) Forum, based on ETSI TS 102 527 New Generation DECT (NG-DECT) European standard series.
NG-DECT contains backward compatible extensions to basic DECT GAP (Generic access profile) functionality which allow bases and handsets from different vendors to work together with full feature richness expected from SIP terminals and VoIP gateways.
CAT-iq defines several profiles for high quality wideband voice services with multiple lines, as well as low bit-rate data applications.
The DECT Forum maintains CAT-iq 2.0 Certification program, which opened in December 2010 for member companies.
[2] Certification ensures feature compatibility between devices from different vendors with specific focus on the over-the-air protocol, RF emissions and wideband audio requirements.
