Customers of Geek would know that now a big push for Geek is PBX, particularly the VOIP PBX, we offer 3 brands and I will get into more detail about that later.
One brand we offer to the very small business is Asterisk. This solution, like any VOIP sultion is 90% networking and 10% telephony.
Well one of the things that makes the networking side of it so hard is that SIP, Skinny and other phone control protocols are cumbersome and messy.
SIP (Session Initiation Protocol) uses a shotgun approach, via RTP (Real Time Protocol) to get the message across, in Astersisk the default ports that need to be punched through your firewall are: 10,000-11,000 (look in your /etc/asterisk/rtp.conf)
Most routers and firewalls don’t like this and can lose track easily. Particularly when NAT (network address translation is involved)
The answer to this with SIP phones is to: Continue reading ‘IAX2 vs SIP,’
I posted this in my favourite Asterisk forum: PBX in a Flash…
But I thought I would post it here as well:
Installing wideband (g722) codec translation in Asterisk 1.4.x
To install g722 as an available codec first install the backport patch: (usual disclaimers apply – it worked for me and did not ruin my pbx, use at your own risk)
cd /usr/src/asterisk
wget http://carlton.oriley.net/drupal/fil…7.1-g722.patch
patch -p0 < asterisk-1.4.7.1-g722.patch
make
make install
amportal restart
to see if it worked, jump into the console:
Asterisk -r
and then type
core show translation
along the bottom of the table alongside g722 you should see a row of numbers (the lower the better ) if you see dashes, the install didn’t work.
You will of course need to use the allow=g722 statement for the protocols you require:
sccp.conf, sip_custom.conf & iax_custom.conf
Plus any extensions for which you have used the disallow statement.
Bear in mind of course, there aren’t too many phones that support wideband as yet…

I thought I would start my return to the blogosphere with a post about how I think DR plans should be constructed.
I recently posted to the SA SBS User’s group about an alternative way of thinking about server imaging. I think some people got it, and some didn’t. I didn’t want to ruffle any feathers or anything silly like that, It’s just that obviously sometimes I don’t make my self clear.
A poster asked what imaging product provides the fastest recovery in the event of a meltdown for SBS2003.
I based my answer on the following assumptions: Continue reading ‘Disaster Recovery’
When it comes to blogging…
Being a technophile, I thought it best to reactivate my blog and get cracking…
I thought I would start my return post with my thoughts on disaster recovery
Formatting is done, just need to populate the content!!!
Doing a website for a client tonight, thought I would try and beat my 6 hour record!
I’ll let you know when I’m done… 
some may know i got a nifty new phone this week. A new nokia n95.With gps and 3g. And a 5 meg camera i seems like a good phone. I an yet to iron out many issues though. I an hopefull that the new firmware due this week will sort out a lot of them.
Anyway i an attempting to up load a photo. So see how it goes.
Well, I have to get this out of the way.
I am going to use this blog to record thoughts. Mainly of a technical nature.
So it’s done.
