sems prereqs:
g++ (>= 3.4)
make
optional:
libspeex (speex codec)
liblame (mp3 file writing)
python (>= 2.4) (ivr, py_sems)
sip4 (py_sems)
mpg123 (mp3 playback)
libresample (resampling)
spandsp (other DTMF detector)
No source RPMs for the moment online. Getting sems source
svn head:
$ svn co https://svn.berlios.de/svnroot/repos/sems/trunk
svn snapshot:
$ wget
http://ftp.iptel.org/pub/sems/daily-snapshots/sems-trunk-latest.tar.bz2
installing sems:
cd sems-trunk ; PREFIX=/usr/local make install
(it is nicer to have all modules built but to make only the needed
modules for vm+conf+anouncement:
make -C core install PREFIX=/usr/local
make -C apps install PREFIX=/usr/local \
modules=announcement conference voicemail
)
some things to configure for voicemail+conference+announcement (todo:
script this):
/etc/sems/sems.conf:
load_plugins=wav;ilbc;gsm;speex;adpcm;announcement;conference;voicemail
sip_port=5070
/etc/sems/etc/voicemail.conf:
smtp_server=mail
smtp_port=25
thats it.
