SIP over TCP in Asterisk

Do sip.conf treba:

tcpenable=yes ; Enable server for incoming TCP connections (default is no)
tcpbindaddr=0.0.0.0 ; IP address for TCP server to bind to (0.0.0.0 binds to all interfaces)

Do users.conf pre jednotliveho uzivatela, pripadne globalne do sip.conf treba:

[6000]
...
transport=tcp
...

iLBC & SPEEX kodek na Asterisku

Kodeky s ktorymi som experimentoval hlavne koli potrebe co najmensieho datoveho toku pri telefonovani cez 3G siete.

Instalacia iLBC kodeku

Od 1.6 verzie Asterisku nie je iLbc standartnou vybavou, treba stiahnut rucne.. Asterisk ma na to vsak pripraveny script, kde po odsuhlaseni licencie stiahne vsetko potrebne:

cd /usr/src/asterisk-*/
./contrib/scripts/get_ilbc_source.sh
./configure
make menuconfig (vybrat iLbc v codecs sekcii)
make install

Nasledne treba povolit codec bud globalne v sip.conf, alebo pre kazdeho uzivatela zvlast:

disallow=all
allow=ilbc
allow=dalsikodek

A nakoniec kontrola:

asterisk -vvvvvvvvvvvvvr
load codec_ilbc.so
core show codecs
core show translations

Instalacia SPEEX kodeku
Na Debiane napiseme nasledovne:

aptitude install speex libspeex-dev

Potom je potrebne skompilovat Asterisk. Najprv spustime ./configure a nasledne v menuconfig oznacime podporu kodeku SPEEX v sekcii Codec Translators. Nasleduje obligatne make a make install.

V pripade,ze uz mame Asterisk skompilovany a kodek chceme pridat, musime spustit make distclean, aby sme Asteriska prinutili si podporu SPEEX natiahnut.

V pripade potreby rucnej kompilacie kodeku, je potrebne stiahnut si zdrojaky z adresy:

How to Boinc on Linux (Debian)

At first:

aptitude install boinc-client boinc-manager

Then you have to create password for localhost, so open file and write your password on it.:

vim /etc/boinc-client/gui_rpc_auth.cfg

Restart client:

/etc/init.d/boinc-client restart

Next we want to attach to some Boinc project.

Find out your account key:

boinc_cmd --host localhost --passwd your_localhost_password --lookup_account http://einstein.phys.uwm.edu/ account_name account_password

Connect to project with your account key:

boinc_cmd --host localhost --passwd your_localhost_password --project_attach http://einstein.phys.uwm.edu/ your_account_key

Check Boinc state:

boinc_cmd --host localhost --passwd your_localhost_password --get_state

P.S.
Boinc client and his tasks usually running with nice 19.
