2. Pre-Installation
Before installing handsets in a VoWiFi system, make sure that all equipment is available. It is
recommended to set up chargers and charge the handset batteries before installation, and
to have a number plan available for the handsets. Also be sure that the IP addressing plan is
set up to support the amount of handsets to be deployed.
We assume that the VoWiFi system is installed including some or all of the following
components (depending on system configuration):
• VoIP Gateway. This is the gateway for ISDN primary rate interfa
ces (PRI) in the Ascom
VoWiFi. It serves as a link between traditional telephony and VoWiFi telephony.
• DHCP Server. A DHCP server allows devices to request and obtain an IP address from a
server which has a li
st of addresses available for assignment. If the WLAN does not have
access to a DHCP server, a list of static IP addresses is necessary.
• Portable Device Manager. The
PDM i
s used for administration and programming of the
handsets. All settings and updates are in this case done via the DP1 Desktop
Programmer cradle connected over USB.
• IMS3. The IMS3 handles all communication b
etween the WLAN and its built-in Device
Man
ager. Before installing the handset, make sure the IMS3 IP address is available.
For effective administration of a VoWiFi system with several handsets, it is required to have
bo
th a PDM and a Device Manager included in the IMS3. In this case, the PDM is only used to
allow the handset to access the WLAN system. All other settings and updates are done with
the Device Manager in the IMS3.
