Introduzione

attachment:ekiga3.png

Ekiga è l'applicazione per le video chiamate su Internet (VoIP) predefinita in Ubuntu. Utilizza gli standard aperti SIP e H.323 e permette chiamate audio e video da e verso tutte le applicazioni software e apparecchi telefonici compatibili con uno di questi due standard. Per effettuare chiamate verso i telefoni fissi e i cellulari, è inoltre necessario essere abbonati a un servizio VoIP che offra questa possibilità. Ekiga non è compatibile con Skype, Google Talk e MSN Messenger.

Usarlo per la prima volta

Quando si avvia Ekiga per la prima volta, il wizard ti aiuterà a configurare correttamente Ekiga in 10 passi . È fortemente raccomandato completare la procedura.

Quando la procedura è conclusa e se si ha un account ottenuto da http://ekiga.net, è possibile procedere con il test eco: sip:500@ekiga.net. È necessario controllare se si ha la possibilità di raggiungere il servizio (la rete SIP), se le impostazioni audio sono ok (è possibile sentirvi con un ritardo), se la webcam funziona (potete vedervi).

Come impostare un account Ekiga.net

Una volta registrati in http://ekiga.net, andare al menù Modifica → Account → Aggiungi

• Nome account: "ekiga.net” o qualsiasi altra cosa

• Registrar: ekiga.net

• Utente: Il nick scelto su ekiga.net
• Password: Password scelta su ekiga.net attachment:ekiga.png

Configurazione

Rete

Ekiga è in grado si usare il server STUN. Nella maggior parte dei casi dovrebbe andare bene anche con NAT.

Suono

Testare il computer

Per controllare se il computer ha i requisiti per Ekiga, digitare questo comando in un terminale:

$ arecord -D plughw:0,0 -c 1 -r 8000 -f S16_LE - | aplay -D plughw:0,0 -c 1 -r 8000 -f S16_LE -

Ora, provare a chiamare sul proprio microfono, dovreste sentirvi con un piccolo ritardo (approssimatamente mezzo secondo). Se non funziona come previsto, provare prima a configurare ALSA:

$ alsamixer

Assicurarsi che il microfono non è nella modalità silenzioso ed i livelli del volume sono giusti.

Ekiga e altre applicazioni audio

Ekiga è capace di funzionare simultaneamente con altre applicazioni audio (come i player musicali). The following directions should be enough to accomplish this if you are using Dapper Drake:

Go to the menu Edit → Preferences → Devices → Audio Devices

• Select "ALSA" as the audio plugin

• Select "Default" as output

• Select "Default" as input

Then go to the menu Edit → Preferences → General → Sound Events

• Select "Default" as alternate device output

For additional help using Ekiga simultaneously with other audio applications, see [http://wiki.ekiga.org/index.php/Getting_several_applications_using_the_sound_card_at_the_same_time_%3F Ekiga's wiki].

Webcam

Note : Ekiga does not require a webcam.

Choosing the right kernel API

The Linux kernel has two ways to communicate with video devices, the old v4l and the new v4l2. It's best to use v4l2, but some drivers only support v4l.

Go to the menu Edit → Preferences → Devices → Video device

• Try "v4l2” or "v4l” as video plugin

Choosing the right video device

If you have several video devices (like a TV card and a webcam) you will need to tell Ekiga which one to use:

Go to the menu Edit → Preferences → Devices → Video device

Change the channel number until you find the right one.

Test your webcam

To test your webcam you can do this:

There are 6 icons on the left side of the main Ekiga window. Push the 4th button from the top (a grey round webcam). If eveything is ok, you'll see the output of the webcam. If not, you'll see the Ekiga logo bouncing slowly.

Ekiga.net special numbers

Echo service

Once you're registered to http://ekiga.net, you can test your setup and line quality by dialing the echo service: sip:500@ekiga.net.

Audio conference server

If you are using 'ekiga.net' as your VoIP provider, you can access a conference server via the aliases

• sip:501@ekiga.net to join the public conference room

• sip:501XXXX@ekiga.net where XXXX is the number of your choice representing the number of the room.

[For example, a group of friends could meet in conference room 1122 by dialing sip:5011122@ekiga.net]

These rooms are thus semi-public/semi-private since anyone can join a conference room at any time if they choose the right number.

Broadvoice Support

In order to setup Ekiga 2.03 to work with broadvoice, use the following settings.

Figure out which proxy is closest to you:

# proxy.lax.broadvoice.com

# proxy.dca.broadvoice.com

# proxy.mia.broadvoice.com

# proxy.atl.broadvoice.com

# proxy.chi.broadvoice.com

# proxy.bos.broadvoice.com

# proxy.nyc.broadvoice.com

Ekiga Preferences:

• SIP Settings -> Outbound SIP Proxy: proxy.broadvoice.com

• Codecs -> Video Codecs - Disable (uncheck) video support or else you will get a codec error.

Account Information:

• Registrar: sip.broadvoice.com

• User: <10 digit broadvoice telephone number>

• Password: <obtained requesting it from broadvoice support>

• Authentication Login: <10 digit broadvoice telephone number>

• Realm/Domain: sip.broadvoice.com or BroadWorks

In the case where you need to troubleshoot, start ekiga with 'ekiga -d 4'

Interoperability

You'll find [http://wiki.ekiga.org/index.php/Which_programs_work_with_Ekiga_%3F here] a list of programs which can work with Ekiga.

Development Snapshots

You can get the latest development snapshots from here: [http://snapshots.voxgratia.org/] Installing them may solve problems you are experiencing but be aware that the snapshots could also cause more problems. A good thing to do before installing snapshots is to uninstall all pwlib, opal and ekiga packages that may already be installed.
