[OpenSIPS-Users] Unable to start a freshly-installed Opensips

[mnemonic.fx at gmail.com]

First of all, to check for any errors on opensips startup, change this
line on /etc/opensips/opensips.cfg:

log_stderror=yes // to log into std error output.

start opensips by calling the binary directly,
$ sudo opensips

You can also check system log by:
$ tail -f /var/log/messages

If this is not enough, change:
fork=no, so the opensips would not fork into another process, to ease debugging.
debug=3 into 4, or anything that suits you
