Configuration und Administration Aspects
This chapter provides detailed information on various configuration and administration
aspects regarding the SIP – DECT solution.
7.1
IP Signaling and Media Stream
To establish a call between an IP Phone and a PP (e.g. Aastra 620d), the following IP
streams must be established:
•
A signaling channel to and from the SIP phone.
•
A signaling channel to and from the OMM.
•
A control interface between the OMM and the RFP that has a connection to the PP
(known as the primary RFP).
•
A Real Time Protocol (RTP) / Real Time Control Protocol (RTCP) connection between the
SIP phone and the primary RFP.
The following figure illustrates this scenario.
To establish a call between two PPs, the same IP streams must be established like in the
scenario before, except the IP phone is not involved. The following figure illustrates this
scenario.
