voudp - VoIP for NetBSD

Building:

1.  Build speex.  This was developed against speex-1.0.3, built from
    pkgsrc/audio/speex

2.  If it's installed somewhere strange, fix the Makefile to find the speex
    library and headers.

3.  Run make.  gmake doesn't work right, because the default .cpp->.o rule in
    gmake doesn't pick up CFLAGS.

Installing:

1.  Install a sound card that can natively do 8kHz 16 bit signed linear stereo,
    both recording and playing.  Make sure your driver announces itself as both
    "full duplex" and "mmap".

2.  Apply the following patch from 1999, to allow mmapping of the record buffer:
      http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=6827
    Rebuild your kernel, and reboot.

3.  Add a group voudpd

4.  Add a user voudpd (shell /sbin/nologin, group voudpd)

6.  in /etc/rc.conf, add:
      voudpd=YES   voudpd_flags="2074 500"
    or some similar flags

7.  ln -s /path/to/voudpd      /usr/local/sbin
    ln -s /path/to/voudpconfig /usr/local/bin
    ln -s /path/to/rc_voudpd   /etc/rc.d/voudpd

8.  mkdir /etc/voudpd
    echo max_packet_len 300 max_buf_ms 20 host localhost port 2074 >
       /etc/voudpd/local
    or some such

8.  /etc/rc.d/voudpd start
    voudpconfig local start

You don't have to create /var/chroot/voudpd, or /var/log/voudpd, as the rc
script, or voudpd itself will create them with appropriate perms if they don't
exist.
