2 Getting Started
This chapter describes how to set up a small SIP – DECT system using two RFP devices,
useable as a small stand-alone DECT telephony system or for evaluation purposes.
Prerequisites
Some hardware and software prerequisites are to be met to follow this quick start guide:
• two licensed RFP devices (RFP L32 IP),
• a PC to run a browser or start java programs,
• a PC-based server for setting up DHCP/TFTP,
• two or more DECT handsets (preferably two Aastra 610d/620d/630d),
• OMM-SIP installation medium with software, such as the “omm_ffsip.tftp” file,
• optional: a VoIP communications system that provides SIP accounts.
You can use any operating system for the PC-based server system that provides a DHCP
and TFTP server. However, the following description details on a Linux system. For testing
and evaluation, you may download and install virtualization software for your workstation,
such as “VmWare Player” or “VirtualBox”. Within a virtual machine, you are able to operate a
Linux system, for example the CentOS, Debian or Ubuntu “Live-CD” ISO files that are
downloadable for free on the respective Linux vendor web sites.
2.1 Setting up DHCP / TFTP
An RFP in the factory default configuration will request the address configuration via DHCP.
While it is possible to configure a fixed (non-DHCP) address for the RFPs (see chapter 7.6),
this description starts with setting up a DHCP server that will answer the DHCP requests.
The DHCP server will be limited to answer only DHCP requests from Aastra RFPs (sorted
out by MAC address), so the new DHCP server will not disturb the operation of possibly
other DHCP servers in your LAN:
Also you need at least a TFTP server that offers the firmware file for the RFP. The IP
address and the firmware file download location is part of the DHCP answer, the RFP
receives during start-up. By using this DHCP-provided configuration, the RFP downloads the
firmware file and starts the software program that is included in the firmware file.
As stated earlier, the PC server system described here is operated by a Linux system. If you
run Linux in a virtual machine, the virtual machine’s network adapter should be configured for
the “Bridged Mode” which allows the virtual machine to receive/answer DHCP broadcasts on
the physical Ethernet adapter.
