  • http://www.cisco.com/
  • Cisco routers are exceptionally good for VoIP as cisco make an extensive range of VoIP infrastructure of their own and are a big player in the VoIP market, however these routers are also very expensive and require some expertise to configure. The configuration is a language in itself which while not hard to learn, does require a very good understanding of IP to get the maximum benefit from.
  • All Cisco routers that run Cisco IOS can support VoIP to various degrees ranging from the 800 series up. Basic featuresets support packet filtering (and maybe NAT payload translation, I'm not sure if it is in the base featureset or requires an advanced firewall set).
  • Purchasing a firewall or Advanced Security featureset license gives you *much* better firewalling capabilities. The firewalling code does full SIP inspection which can help prevent an attacker from hacking in via SIP (unlikely as it is). More importantly it adds the capability of the router to dynamically open and close TCP/UDP ports through an otherwise fully blocked off firewall (ie deny ip any any) for the SIP control stream of a call, and including the RTP stream which uses dynamic high UDP ports, and additionally does full NAT translation of the UDP payload of SIP requests in and out. This means you will need to make no configuration changes for NAT to your VoIP server even if it is on a private IP range as the router handles everything for you. It also means you can have a virtually unlimited number of phones behind one of these devices all making calls at the same time without having to add NAT rules for each individual one.
  • Full QoS, allowing you to prioritise SIP payloads and SIP RTP streams over all other traffic, reserving bandwidth for voice streams when a voice call is in progress.
  • The usual modules for cisco routers, ADSL, ADSL2, ISDN, POTS V.92 modem, E1, serial etc.
  • Full routing capabilities, RIP, RIP-II, EIGRP, OSPF, BGP, IS-IS, IPSec depending on what featuresets are purchased.
  • Models starting from the 1760, 2600, 2800 series and above also support FX0/FXS/E&M ports onboard.

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.

Re: BT Voyager 220V - how to configure for Asterisk/SIP Provider

by Rikard on Monday 23 of April, 2007 [14:34:12 UTC]
I've only been able to find a bit of info about the BT Voyager 220V on the net so in the end had to experiment myself. After a load of tedium I got it to work fine and now have two internal extensions connected to Asterisk via the 220. Here is how I did it. No knowledge is assumed so I've tried to include everything:-

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?

Hi did the firmware update telnet to router, used the voice set commands, but whatever I have tried I cant get the voice set obproxy to register after saving the config if I do voice show, sip outbound proxy line is still empty and if I try to restart the voice application on the router its coming up with SIP outbound proxy server is not configure!!

what would be the problem??

Re: BT Voyager 220V - Anyone know how to configure it?

by jason on Tuesday 04 of April, 2006 [09:55:10 UTC]
You need to upgrade the firmware to SIP protocal with here;

http://www.voyager.bt.com/firmware_upgrades/cfe-voyager220v_sip_btr-v301n_a2pb018c1

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

Jason

BT Voyager 220V - Anyone know how to configure it?

by Bernard J Abbott on Tuesday 11 of October, 2005 [10:57:16 UTC]
This is a VOIP enabled modem/router supplied by BT. The BT Business Broadband Voice web-site has a high level user manual etc. but there is virtually no information about configuring this unit for other SIP providers. I gues BT don't want to tell anybody!! I don't think that it is locked. Does anyone have any further info on this unit, or details of its manufacturer. There are plenty for sale inexpensively on e-bay, perhaps because many swap it out for a wireless gateway. Would be good to have real gen on this item on this site.
