IP signalling and media stream
To establish a call between an IP Phone and an DECT handset, the following IP streams must
be established:
●
a signalling channel to and from the IP phone
●
a signalling channel to and from the ADMM
●
a control interface between the ADMM and the IP DECT base station that has a
connection to the DECT handset (known as the primary IP DECT base station)
a Real Time Protocol (RTP) / Real Time Control Protocol (RTCP) connection between the IP
Phone and the Media Gateway and then a RTP/RTCP connection between the Media Gateway
and the IP DECT base station.The following figure illustrates this scenario.
