Appendix: IP Signalling and Media Stream
If the DECT phone user is moving, the phone detects that another IP Base Station has a better signal strength and starts
the handover process. The media stream from the IP phone cannot move to the secondary IP Base Station, so the
primary uses the LAN to direct the voice to the secondary IP Base Station, as shown in the following figure.
As the phone user moves into the next IP Base Station zone of coverage, the phone detects that the IP Base Station has
a better signal strength. The media stream from the IP phone cannot move to the secondary IP Base Station, so the
primary IP Base Station uses the LAN to direct the voice to the new secondary IP Base Station, as shown below.
