Summary

The Linksys RTP300 is a 4-port Ethernet router with two built in phone-lines. Each phone line has a corresponding RJ-11 jack on the back of the device where you can connect any regular analogue phone.

The RTP300 is often provided to customers by SIP providers as a cheap HW solution to get started quickly with whatever phone you already have at home. If you are registered with a SIP provider chances are that you already have one at home.

This device supports all common protocols, but this page describes how to use it as a SIP device. It is not PnP in LinuxMCE, but with some simple manual steps it can easily be integrated in your LinuxMCE system. This page describes how.

Setup

Obtaining administration password

The first step is to gain access to the administration web page of the device. If you bought it yourself, you can use the default user/pass and you are good to go. If you got it from a SIP provider they have most probably changed the password to prevent customers to configure the device with another provider.

In the latter case there exist a number of possibilities to get the password. First, try and search the internet, chances are that the passwords have leaked and are actually published on the net. If you can not find it with Google, contact the tech support of your provider. Explain what you are doing, and that you do not have the intention to sign up with their competition. It is of course a long shot to do so, they are likely to let you down (although this is actually how I got the passwords). As a last resort this link explains how to unlock the device by flashing it with the latest firmware. Bear in mind that any provider specific information will be lost if you choose to do so. I haven't tested this myself, but the procedure includes actually editing the binary firmware by hand before flashing. So it is probably not something for the faint-hearted.

In any case, there are three passwords needed to perform the necessary configurations of the device:

1. Main access to the web administration tool

2. User level access to the voice part of the device

3. Administrator level access to the voice part of the device

These three credentials may or may not be the same.

IP and MAC address

Connect the internet port of the device to your LinuxMCE subnet. Connect one of the four ethernet ports to a computer. Open up a web browser in the computer and type in the web address of the device. The default address is http://192.168.15.1 . Your SIP provider may have changed the default ip to further confuse curious customers. If this is the case you can e.g. examine the ip configuration of the computer that you hooked up to the device. Since the computer is connected to the RTP300 subnet its ip address can give a hint. If the ip of the computer is e.g. 192.168.75.XXX, then there is a big chance that the ip of the device is 192.168.75.1. When you have figured out the ip you should get a welcome screen similar to

Type in the credentials and hit "Login". Start by hitting the Status tab, and you should see something like this
