Hello,
I know that I am attempting to do is not the usual job of Linphone, but
perhaps somebody here can show to me a solution to my problem. Please, have
a look here http://cherchetout.pagesperso-orange.fr/FaxOverVoIP.html and
mainly at the end part which is written in blue characters. I beg your
pardon for this is not in english...
Using linphonecsh, I recently found a way to make linphonec sending RTP
packets with constant intervals of 20 ms (or 30 ms depending on provider and
time of day) ± epsilon with epsilon < 1 ms.
After having begun a session and registered, I simply initiate a call like
this :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
linphonecsh generic "soundcard use files"
sleep 0.1
linphonecsh dial sip:address@hidden
sleep 1
linphonecsh generic "record /dev/shm/received.wav"
aplay -D hw:0,0 -f S16_LE -c 1 -r 8000 -t wav --buffer-size=96
/dev/shm/received.wav &
arecord -D hw:0,0 -f S16_LE -c 1 -r 8000 -t wav --buffer-size=96
/dev/shm/sent.wav &
linphonecsh generic "play /dev/shm/sent.wav"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Unfortunately, this improvement doesn't allow me to send faxes, but I think
I have identified the true problem and I shall explain this soon in this
list because only a developer could resolve it.
