12 Product overview
Use the SIP Redirect Server or SIP Proxy Server to perform the
appropriate NRS configuration for SIP DECT. You can run SIP
Redirect Server on Internet Server Platform (ISP) 1100, Call
Processor Pentium Mobile (CP PM) signaling server, or on IBM or HP
Commercial-off-the-shelf (COTS) servers under VxWorks. You can run
SIP Proxy Server on IBM or HP COTS servers under Linux. You can

a stand-alone COTS server. You cannot run SIP Gateway on the same
server as the SIP Proxy Server.
