" PURPOSE: \n"
" sipnagios is a modification of the original siprtp sample in pjproject \n"
" \n"
" siprtp original blurb: \n"
" This program establishes SIP INVITE session and media, and calculate \n"
" the media quality (packet lost, jitter, rtt, etc.). Unlike normal \n"
" pjmedia applications, this program bypasses all pjmedia stream \n"
" framework and transmit encoded RTP packets manually using own thread. \n"
" \n"
" sipnagios blurb: \n"
" sipnagios implements the Nagios plugin API for monitoring and \n"
" performance data. It makes a call, checks all the various resulting \n"
" values (mos, rtt, pdd, tta, jitter, packet loss, bytes and packets \n"
" transferred, and so on). It verifies these values are included into \n"
" acceptable, warning, or critical ranges. If the call has gone well,\n"
" sipnagios print performance data for Nagios graphs, and returns 0.\n"
" If the call fails, or if its measured values are not inside acceptable \n"
" ranges, it exits with Nagios conventional WARNING or CRITICAL values.\n"
" \n"
"\n"
" USAGE:\n"
" sipnagios [options] SIPURL\n"
"\n"
" Call options:\n"
" --duration=SEC, -d Set maximum call duration in seconds (default:40) \n"
"\n"
" Address and ports options:\n"
" --local-port=PORT,-p Set local SIP port (default: 5060)\n"
" --rtp-port=PORT, -r Set start of RTP port (default: 4000)\n"
" --ip-addr=IP, -i Set local IP address to use (otherwise it will\n"
" try to determine local IP address from hostname)\n"
"\n"
" Local user options:\n"
" --local-user=USER, -u Set local SIP user (default: alice)\n"
" --local-password=PASSWD, -w Set local SIP user password (default: 1234)\n"
" --local-siprealm=REALM, -s Set local SIP user SIP realm (default: atlanta.example.com)\n"
"\n"
" Logging Options:\n"
" --log-level=N, -l Set log verbosity level (default=1)\n"
" --app-log-level=N Set app log verbosity (default=1)\n"
