step 3:launch linphone on gnome:

Applications -> Internet -> Linphone


step 4: configure the Linphone

Go -> Preferences -> Network
Nat traversal options -> Use this stun... : stun.sipgate.net:10000
leave all other default settings

Go -> Preferences -> SIP
Identity -> Your Sip address : sip: XXXXXXXXXXXXXX @ sipgate.de
remove the check from : Automatically guess a valid hostname
Remote services -> add proxy/registar
sip identity: sip:YYYYYYYYY@sipgate.de
sip proxy: sip:sipgate.de
leave all other default settings

you should be prompted with another box with asking for the following:
realm="sipgate.de"
username=YYYYYYYYY
userid=YYYYYYYYY
passwd=ZZZZZZ

In the end you should see an account inside the Remote services box with:
sip: YYYYYYYYY@sipgate.de

apply the configurations and close.

You should now be registered sucessfully on the provider softswitch.


step 5: check/audit your settings is by looking at the following configuration file:

Angola - growing but in what direction ?

* Don't know Angola. Never been there. I know many people from Angola, though!
* Portuguese and Angolans, claim that Angola it's a country with lots of natural beauties and opportunities
* Portuguese and Angolans that know, tell me about the horrible stories about corruption (mostly from the government elite), that stop the sustainable development of this "rich" country...
* Many emergent rich people from Angola (mostly with responsibilities in the government) are expending fortunes buying houses, cars, superfulous goods and let the rest of the population without basic food and services...
* My opinion: as long as there are these kind greedy people that only think of immediate profit and well being for themselves, the poorer will suffer more and more!
This applies both to Angola, which is experiencing at the present time economical growth, and to Portugal which has been living in democracy since 1974, and which claims to be a developed country in Europe!
* you will find on the net other people with comments relative to the "growth" of Angola (eg. here).
And of course the usual news massmedia channels will "skip" these issues that are not "political correct"

quem só de Direito sabe, nem de Direito sabe

Preocupam-me hoje as seguintes questões, por força da minha actual vivencia:
- Quais as diferenças entre um bom gestor e um gestor Portugues ?
- Porque razão é que um gestor Português em Portugal arroga para si o direito de ganhar muito bem, e mantem os seus colaboradores "alimentados" a "tremoços" ?
- Porque razão é que um gestor Português "pensa" que os gestores estrangeiros nao percebem nada do "assunto" ?
