Armadilla Garden Office Installation Video


Looks precarious... but here is a 10 minute video of our Armadilla office installation.

If anyone has any questions on how this all worked, feel free to drop me a comment.

Armadilla - IP Phone - BT HomeHub 2



Regular phones over Ethernet
(if you dont like tech geek stuff... stop reading now!...)




I decided to give Voice over IP (VOIP) a shot in my new garden office.  I also wanted to use my existing regular (POTS) telephone line for incoming calls.   I bought a Linksys (Cisco) SPA3102.  This box is designed to allow you to plug your phone sock in, and for the signal to be converted to IP traffic.  The protocol is SIP...

The S in SIP does not mean 'Simple'.

After a week or so of faffing around, I discovered that the BT HomeHub that I have has some 'partial' SIP server support, and as a result seems to block / catch my SIP traffic. So... calls coming into my Linksys SPA3120 don't go any further than my BT Homehub.   As I am using that as my router... it means the traffic getting out to my Ethernet over Power adapter.

BT used to provide a services called BT Talk. This was basically their version of SIP running over the broadband connection.   If you have a BT Homehub 1 or 2... you can still use it.  If you are on the Homehub 3... sorry it was removed from the device.

The phone number you get with this is different.  I have a regular phone number - that comes through my regular phone... and a BT Talk phone number.  They both start with the same area code... 


Anyway - I decided to switch this on... only problem is... that I want to use a device other than a BT IP phone... I want to use my iPad or Mac Book pro to send and receive calls...


After searching around the BT Broadband forums, I discovered that you can download the SIP settings to a text file... and that will give you all the information you need to setup your SIP client....  I am using Jitsi as a SIP client - that seems to work.  I have also managed to get X-Lite 4 to work... but it is not quite as solid as Jitsi as far as I can tell.



so... I now am able to make SIP calls from my mac book pro (or iPad).

For the geeks out there, this is how you find out your SIP Softphone Client settings.  This is for anyone that has a BT Homehub 1 or 2 (pulled from the BTBroadband Forums);

1. Sign up for BT Talk...



https://service.btbroadbandvoice.bt.com/bbv/online/consumerBBTalkMyAccount

a) Enter your number and login details - they were sent to you when you registered,
b) Navigate to configure your setup, click the First Button "Configure Your equipment"
c) A Second button appears call "configure"
d) Right mouse click this and get properties
e) Cut and paste the whole URL into a text editor
f) To make it more legible put a carriage return before every "&" the remove the "&"

You will end up with something like this :-

http://api.home/voipsetup.api?
SIPTransportPort=5060&
SIPRegistrarAddress=btsip.bt.com
SIPRegistrarPort=5060&
SIPOutboundProxyAddress=sip.btsip.bt.net
SIPOutboundProxyPort=5060
SIPProxyAddress=btsip.bt.com
SIPProxyPort=5060
SIPPhoneNumber1=44XXXXXXXXX
SIPUsername1=44XXXXXXXXX@btsip.bt.com
SIPPassword1=QMXXXXXXXXXXXXXXXX

2) The most important bit of information is SIPPassword1=QMXXXXXXXXXXXXXXXX. This you will note is NOT the BT password BT gave you which you login into the site, which you might think is encrypted. It's plain text an is the password you need to use to authenticate against the proxy. Also understand that it's important you do not confuse the outbound proxy with the SIP proxy.



This translates to on a SIP Client - replace the values above in the <> entries;


Authentication or Authorization Name: <SIPPhoneNumber1>
Authentication password: <SIPPassword1>
Username: <SIPPhoneNumber1>
Domain: btsip.bt.com
Display Name: <SIPPhoneNumber1>  without the leading 44
Proxy server address: btsip.bt.com
Proxy server port: 5060
Registrar server: btsip.bt.com
Registrar server port: 5060
SIP port: 5060
RTP port: 5004
Use random ports: No
STUN enabled: No
Outbound proxy mode: Always
Outbound proxy: sip.btsip.bt.net
Outbound proxy port: 5060

If you want to use all this without a BT HomeHub.. I believe you can, but, you need to setup a nameserver lookup for the proxy... or something like that... 



Sadly, I have not managed to get my inbound telephone calls on my regular (POTS) line to route through this.  I know the SPA3120 can do it... but I think the BT Homehub is blocking this.  The BT Homehub cannot be configured to route this traffic as far as I can tell... even with a hack.





Armadilla living - 2nd week

As per my previous posts - I installed an Armadilla home office down my garden.

Now that I have been in it for a couple of weeks, I thought I should give others that are interesting in this kind of building some feedback. 

First of all, the heating.

The weather has been mixed.  With an outside temperature of, say 10'c the under floor heating is absolutely fine. It keeps the office warm at around 15-20'c without trouble.  However, you do need to keep some heat on overnight.  I made the mistake of lowering the thermostat over night to 5'c when it was frosty... when I arrived in the morning at 9am it was only 8'c after 1 hour of heating...

That said, this is where my wood burner comes in.  30 mins after starting, the office is back to a pleasant working environment.

I have continued to have issues with connectivity. Nothing to do with the office supplier, but, I made the mistake of only running a 3 core armoured power cable in... as a result, I only have power and no dedicated phone / internet.    Being a geek of course, solutions exist.  Archie suggesting using an Ethernet over Power solution.  I chose the Devolo solution that gives me ethernet ports and wifi in the office. It is mostly working, and performs fine (measured at 6Mb/s download).

Phone though has been less successful.   See my next post on this one!

Armadilla Garden Office - Post Install

Well, I have now been in my Armadilla Garden office for 1 week.   A few things to report, but first of all I want to show you why I put the office where I put it. Here is a picture of the view out my window this afternoon;




No buildings... people... etc... :)     I can only listen to mellow music now!

I have now put more content into the office - some pics of that;

I'm afraid I had to resort to Ikea...  budget restrictions...

Early evening, with porch and internal lights now working

Single door rather than double french door fitted due to extra space required for wood burning stove

The view... clutter arrives!


This might be small, but having run it a few times I can say that this is quite sufficient to turn the office into a sauna!
