Compiling Asterisk on Ubuntu server

I wanted to test something on Asterisk for a project and need it a new clean install.
Instead of setting up another machine i decided to use the power of my desktop machine ( an intel quad core with 8GBram) and go for a VM.
I decided to use QEMU for the VM as i am using it for embedded development for sometime now and it has proven a very reliable tool (plus its free :)
I created an Ubuntu server on the VM, but then i realized that the asterisk packages shipping with Ubuntu server were rather old.
So i downloaded asterisk, asterisk-addons, libpri and zaptel and started the building process.
For those of you who decide to go the same way, following are the packages you need to get asterisk with realtime (aka mysql support) to build.

sudo apt-get install build-essential speex libspeex-dev gsm-utils \
libgsm1-dev libgsmme-dev libgsm1 libgsm-tools \
libncurses5-dev ncurses-term libncurses5-dbg libsqlxx-dev doxygen

You will also need to install the linux kernel headers
so do a 'uname -r" and then

sudo apt-get install linux-headers-your-kernel-version-here

Once all these get install, follow the standard procedure to build libpri,zaptel,asterisk and asterisk-addons

Altec Telecoms - Charges beyond the "grave"

To many of you who do not know it, Altec Telecoms *WAS* a Greek VOIP provider that went bankrupt a couple of months ago.
I was using their service, a pre-paid one, and i was paying using PayPal for a DID line plus the costs of the calls i was making.
When it wend bankrupt, services to customers terminated and i had something in the range of 30 Euros pre-paid to them, which i pressumed that had gone to the "never-never land"
Then i started receiving these emails
To those of you that the first part looks...Greek, don't worry it is :)

English text follows

A charge notification from a bankrupt company, that has shutdown operations !!!???? WOW !

Well it looks like Altec Telecoms is now in a "zombi" state, as the people who worked there have "taken over" the installations in order to "protect the company assets until the bankruptcy court comes out with a decision" i.e get some money as compensation.

The weird think is that although i can not connect to their sip.server, they still have internet connection and can send emails and also their TDM lines are working, so when you call the DID assigned to you get directed to the voicemail...

I thank God, i decided to go with the pre-pay plan and pay with Paypal and not with a contract/monthly credit card charge, as i believe i would have seen charges been applied to the credit-card and then go though the pains of contacting the bank for canceling them....

My .2 euro cent advice to Altec Telecom customers paying with credit card... check your credit card statments.
