Linphone is a Voice over IP ( VoIP ) application. Its purpose is to make phone calls over the data network, instead of using the telephony network.

SHR-U

Linphone is still not in the SHR-unstable repository but can be built following Building SHR with cd shr-unstable/openembedded/recipes/libosip2 ; cp libosip2_3.1.0.bb libosip2_3.3.0.bb ; cd ../../.. ; bitbake linphone

My linphone packages is here [1] Because of alsa audio errors printed when running witch can be seen if running from commandline, I had to move away mv /etc/asound.conf /etc/asound.conf.bak and then put it back when done. If this is not done it get overloaded by printing the error message. I also remember there was some problem with the mic audio setting. Maybe some could add this here or maybe the koolu setting below is working. I have not tried it yet.

Qtopia

Here is a way to get the command line linphone working on Qtopia. Ideally this could be interfaced with the dialer somehow. Download link broken.

echo "src/gz celtune http://rabenfrost.net/celtune/ipk/armv4t" >/etc/opkg/general-feed.conf
opkg update
opkg install libmediastreamer0
opkg -nodeps install linphone
opkg -nodeps install liblinphone2 linphonec linphone-rings
opkg install libexosip2

cd /etc/
wget http://www.koolu.org/asound.conf
wget http://www.koolu.org/voip-handset.state

alsactl -f voip-handset.state restore # This step required to set proper audio parameters

linphonec
soundcard use 0
proxy add

Initial testing of this had the audio routed properly through the earpiece and good audio from the microphone. There was some echo on the non-Freerunner side, and on initial connection, a bit of a beeping sound. Otherwise, it's a go. Linphone uses only about 10-12% CPU (was using a PCM codec). Sound was decent to a cell phone in Canada using a Wifi connected Freerunner based in Costa Rica.

Here is a quick and dirty how-to. Enhancements can be made to both the voip-handset.state and asound.conf files (these were my initial working scripts). Thanks to Celtune for the excellent repository that is used below.

FDOM

If you want to avoid installing linphone you can use the FDOM image. This includes the linphone installation. You just have to enter your sip-account details.

Settings

''Enter proxy sip address:'' sip:sip.provider.com
''Your identity for this proxy:'' sip:xxxxxxxxxx@sip.provider.com
''Do you want to register on this proxy (yes/no):'' yes
''Specify register expiration time in seconds (default is 600):''
''Expiration:'' 600 seconds or so

Asterisk

In sip.conf
