Postup zprovoznění pod Linuxem

Stahneme si ovladac z http://www.openh323.org/driver/code.html, rozbalime a ziskame adresar 'ixj'. V tomto adresari zadame `make ixj-pnp`, v pripade uspesne kompilace dame `make install` a timto se nam nainstaluji prislusna zarizeni v /dev/ a moduly do jadra (phonedev.o, ixj.o).

Jelikoz se jedna o ISA PnP, musime nastavit tuto kartu, takze provedeme:

[root@petulka linux]# /sbin/pnpdump > /etc/isapnp.conf

Dale upravime radek (v /etc/isapnp.conf), ktery se podoba

(CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
              ^^^^^

na

(CONFLICT (IO WARNING)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
              ^^^^^^^

a dale radky

# (IO 0 (SIZE 16) (BASE 0x0300) (CHECK))
 (NAME "QTI0100/339477289[0]{Internet PhoneJACK Audio}")
# (ACT Y)

za radky

 (IO 0 (SIZE 16) (BASE 0x0300) )
 (NAME "QTI0100/339477289[0]{Internet PhoneJACK Audio}")
 (ACT Y)

kde samozrejme nastavime vlastni IO adresu. Je mozne, ze adresa 0x300 se bude hadat se zvukovou kartou, proto si prosim nastudujte dokumentaci z /usr/src/linux/Documentation/telephony/ixj.txt na jake mozne hodnoty to muzete nastavovat. Kartu inicializujeme pomoci `isapnp /etc/isapnp.conf`.

Modul zavedete pomoci `/sbin/modprobe ixj` a muzete vyuzivat IP telefonii. Jak zavest tento modul automaticky si prostudujte ve vyse uvedene dokumentaci.

Timto mame zaveden modul v jadru a nyni potrebujeme nejaky ovladaci software, ktery ziskame na adrese http://www.openh323.org/code.html#source. Potrebujeme PWLib, OpenH323 a dale OhPhone ci OpenAM (AM ~ Answering Machine). Jsou zde predkompilovane binarky, ale doporucuji stahnout zdrojovy kod a prekompilovat u sebe. PWLib a OpenH323 jsou knihovny, kterych vyuzivaji OhPhone, OpenAM a jak tyto knihovny nainstalovat se docete primo v jejich readme (ci obdobnych souborech). Jak zkompilovat, nainstalovat a pouzivat OhPhone, OpenAM se dozvite v jejich readme souborech, manualovych strankach ci primo na http://www.openh323.org.

OhPhone upozorneni Pokud budete vyuzivat tento software a telefonovat na stanice s OS Windows, budete muset zapnout volbu

-f --fast-disable       : Disable fast start

jinak se stanice s Windows zhrouti.

Poznámka

Strcite si telefon do karty a telefonujete, no neni to parada? ;)
