• Aastra SIP-DECT Access Points (also known as Radio Fixed Parts
(RFPs’)) being distributed over an IP network and offering DECT wireless
and IP interfaces.
• A SIP Call Manager/IP PBX/Media Server platform (e.g. Asterisk).
• Aastra DECT 142 Handsets / Aastra 142d (also known as Portable Parts
(PP))

DECToverIP using SIP solution, which runs on one of the Radio Fixed
Parts.
