- Embedded versions run on Soekris Engineering and PCEngines small format boards. Boot from and store setups to CF card.
- includes VPN server and client capability.
- may be configured as router & wifi access point.
- can enforce VPN over wifi
- pfSense (FreeBSD)
- fork of M0n0wall
- pfSense has very nice QoS for VoIP and traffic shaping, different from m0n0wall.
- embedded version runs also on generic PC hardware, but unlike m0n0wall the output is directed to the serial port in this case. Therefore, for the embedded version you need a null-modem cable to connect from the serial port of your PC to the serial port of the router. Under Windows XP you can use HyperTerminal with settings for the serial connection of 9600 bits per second, 8 data bits, no parity, 1 stop bit and flow control set to hardware to see the output when the router boots. On linux you can use minicom as your terminal emulator.

Bandwidth Shapers
StreamEngine-based product
StreamEngine is a technology by Ubicom, that is incorporated in other vendor's network devices. Lets you prioritize your WAN's outbound traffic based on a proprietary protocol. Few adjustements are needed/possible.- Hawking HBB1 Plug and play between router and cable/dsl modem. Works with single WAN IP.
- D-Link DI-102 VOIP Accelerator Same as HBB1, but seems discontinued. Seemingly replace by D-Link's SecureSpot.
- D-Link DI-724GU Wifi Office Router Router that includes the technology, therefore no need for an additional device like the HBB1 or DI-102.
Other technologies
- http://www.netequalizer.com/ implements QOS on existing network
- http://www.packeteer.com/products/packetshaper high-end traffic shaper can prioritise VoIP and many other apps as well as give detailed stats etc.

333Re: BT Voyager 220V - how to configure for Asterisk/SIP Provider
1. As stated everywhere the web interface is no use for this. Telnet into the router. Windows has a basic Telnet built in so just type TELNET 192.168.xxx.xxx where xxx.xxx is the actual IP address of your router. For most people this will be the default IP it comes with. User/Password are the same as the web GUI.
2. You should see a numbered menu but you can ignore that. It's not obvious but you are actually at a linux command line now and the menu just serves as a prompt so you can type commands directly here.
3. Type the following commands carefully and make sure that you have returned to the menu each time as you will get press return to continue type prompts after everything you type.
voice set interface br0 - this changes the interface to use from the external internet link to the internal network
voice set registrar XXX.XXX.XXX.XXX:PPPP - where XXX.. is the IP address of your Asterisk box and PPPP is the port
voice set obproxy XXX.XXX.XXX.XXX:PPPP - as above, your Asterisk box
voice set proxy XXX.XXX.XXX.XXX:PPPP - as above again.
voice set phone1 num:callername:UserName:passwd
voice set phone2 num:callername:UserName:passwd
- num=the section name you have used in the Asterisk sip.conf file
- callername=Asterisk 'callerid' setting
- Username=Asterisk 'username' setting
- passwd=Asterisk 'passwd' setting !! :)
hint - type voice show for a full list of commands available
4. Select option 12 from the menu 'Save and Reboot' and then option 1 to confirm or you have just wasted your time!!
5. In sip.conf in Asterisk I used:
240
; BT Voyager 220V Extension 1
type=friend
regexten=240
username=240
authname=240
callerid=240
PLUS the other usual settings for a SIP extension.
Your router *should* now be setup to use Asterisk. If you have already setup Asterisk then after the reboot you should see the voyager register it's phones.
It's been running fine for a week now but you sometimes need to issue the command 'voice restart' via telnet to the router when you've made changes to Asterisk.
I'm an Asterisk fan but I reckon this method *should* work for any sip service provider. You'll need to leave the interface set to the internet for external SIP providers of course.
Bear in mind that this will disconnect your BT Broadband Voice line as you can only have one VoIP supplier. BT's answer to most problems with BT BBV is to send out a new router so there must be hundreds of redundant ones out there. If you have one use it for the FX ports so you have real phones for your SIP accounts.
This is my first post here so any feedback would be most appreciated especially on if this works with the Home Hub or other voyager type BT kit.
If anyone has problems getting this to work it would be good to know so I can keep this info updated
NOTE: I am still battling to get my Asterisk to use BT Broadband Voice - anyone achieved this and got some info on it?
333Jason
what would be the problem??

You cannot configure the SIP details via the web UI as its locked to BT(ish).
But if you telnet in "telnet 192.168.1.1" you can set all the SIP options with the "voice" command.
Cheers
