SEMS sipp Basic Test Configuration

sems.conf:

- listening at 127.0.0.1:5050 for sip requests from uac
- using 127.0.0.1:40000-49999 for media (if rtprelay enabled)
- adjust plugin_config_path and plugin path to your sems setup

# sems -f sems.conf

uas:

- listening at 127.0.0.1:5052 for sip requests from sems

$ sipp -sf uas.xml -i 127.0.0.1 -p 5052

uac:

- makes one call to uac via sems transparent sbc

$ sipp -sf uac.xml -m 1 127.0.0.1:5050

After basic test works, modify sems and sipp configuration according to
your test requirements.
