Cisco WRP400

From VoIP.ms Wiki

The Cisco WRP400 is a wireless-G broadband router with two phone ports, one wired Internet uplink port and four wired LAN ports. It provides both the networking capability of a standard wireless router and the voice capability of common Cisco/Sipura two-line adapters (such as the SPA112/122 series) all in one box.

Installation

In its default configuration, the WRP400 is configured to be a wired router:

• Internet uplink is DHCP
• Local area network address for configuration defaults to http://192.168.15.1 (username:admin, password:admin)
• The WRP400 provides NAT and a DHCP server to allow wired connection of up to four PCs to one Internet connection
• Wi-fi and telephony are "off" until configured

(As with other Cisco/Sipura adapters, the address of the device (as seen from the outside Internet) may be obtained by pressing * * * * 1 1 0 # from the telephone handset, even if there is no dialtone. This is rarely needed as the settings are normally accessed from the LAN, where "voice" appears as just one extra tab on an otherwise-standard network configuration screen at a known address.)

Various tools are provided to allow portions of the network setup to be automated, including a Windows CD-based programme and a pushbutton on the unit to allow configuration over a wireless connection. It is possible to configure the router without these tools by plugging a PC into one of the wired local area network ports and entering settings manually from a web interface.

As of 2013, these routers continue to being shipped with outdated (version 1.01.00, circa 2009) firmware.

Note that Firefox support in current Cisco offerings is buggy; even with the firmware upgrade the WRP400 will often respond to configuration change attempts from Firefox with "your connection has been reset". It is best to use another browser during the configuration process.

Firmware upgrade

Version 2 firmware for this device was released in August 2012 and may be downloaded at http://software.cisco.com/download/release.html?mdfid=282414113&softwareid=282463656&release=2.00.30

The downloaded file is a .ZIP archive; unzip it. This yields three files; a .pdf of documentation and two .bin files with similar names (but one with "FCC" and the other with "ETSI" in the name). The "FCC" version is for North American users.

Go to http://192.168.15.1/Upgrade.asp (the default local address of the router if you have not changed it) and enter the username/password (by default, admin for both). You will be prompted to "select a file to upgrade the firmware" and press "start to upgrade". Select the .bin file for your region and allow the upgrade to complete.

Once the upgrade is complete, see http://www.cisco.com/en/US/docs/voice_ip_comm/csbpvga/wrp400/administration/guide/WRP400_UG_v2-0_OL-18475-01.pdf for instructions on how to configure the networking features of the WRP400, such as the wireless local area network.

Configuration Details

This section describes configuration of the voice portion of the WRP400 router only. It presumes that you are connected to the router via a PC plugged in to one of the four wired local area network ports. The router is manually configurable at its default LAN address of 192.168.15.1 unless this address has been modified by a previous user configuration change.

Step 1

Power up the WRP400 router and allow it to initialise. Connect a PC to one of the router's local area network ports.

Step 2

Open a web browser to http://192.168.15.1/admin/voice/ and log in with username admin and default password admin.

Step 3

Click on Voice, then configure Line 1 as follows:

Proxy: atlanta.voip.ms (You can choose any of our multiple VoIP.ms servers)

Display Name: Your name

User ID: Your VoIP.MS SIP Account number (or subaccount)

Password: Your VoIP.MS SIP Password

Dial Plan: (911S0|<:1555>[2-9]xxxxxx|1[2-9]xx[2-9]xxxxxxS0|[2-9]xx[2-9]xxxxxxS0|*xx|*xx.|[3468]11|822|0|00|[2-9]xxxxxx|4xxx|**275x.|xxxxxxxxxxxx.)

(note: replace 555 in the dial plan with your area code)

Click Submit to save settings.

Step 4

Click on Voice, then Line 1

If the WRP400 is behind another router (which will rarely be the case) set NAT Mapping Enable to Yes, then set NAT Keep Alive Enable to Yes. If your WRP400 is connected directly to your modem, in most cases you can leave these settings disabled.

Under Proxy and Registration set Register Expires to 180, Proxy Fallback Intvl to 180

Also confirm the following settings:
Use DNS SRV: NO
DNS SRV Auto Prefix: NO

Step 5

Click Setup, then go to Basic Setup, then scroll down to Time Setting

Set your time zone and (optional) NTP settings. A good time server choice is 0.pool.ntp.org. Setting the proper time zone will ensure that the time which appears on your Caller ID display is correct.

Step 6

Click Voice, then go to SIP.

Set SIP Timer Values (sec)

SIP T1: 1

Set RTP Parameters

RTP Packet Size: 0.02

Cisco's defaults (SIP T1 = 0.5 sec, RTP packet size 0.030 on most Sipura adapters) respectively may cause unnecessary retransmission of commands over connections with high latency and create issues with outbound audio "breaking up".
