CAUTION!!
----------
This image is just an easy way to play with this environment. Is _NOT_ for production use.
You still need to implement measures to improve the security.
You have been warned.

Changes needed to use this VM behind NAT
----------------------------------------

The VM needs to be in the router network. NAT should be managed by
the user's router and ports be forwarded to the VM IP.
You can do this by configuring a bridged interface in kvm.

Forwarded Ports:
 - 5061 (tcp) SIP TLS
 - 30000:50000 (udp) Media
   This can be configured at /etc/default/ngcp-mediaproxy-ng-daemon file:
   # PORT_MIN=30000
   # PORT_MAX=50000

* change internal (X.X.X.X) and external (Y.Y.Y.Y) IPs:

# sed -e 's/^##!define WITH_IPEXT/#!define WITH_IPEXT/' -i /etc/kamailio/kamailio-local.cfg
# sed -e 's/IP_INT/X.X.X.X/g' -e 's/IP_EXT/Y.Y.Y.Y/g' -i /etc/kamailio/kamailio.cfg
# sed -e 's/^# ADDRESS=/ADDRESS=/' -e 's/^# ADV_ADDRESS=/ADV_ADDRESS=/' -i /etc/default/ngcp-mediaproxy-ng-daemon
# sed -e 's/IP_INT/X.X.X.X/g' -e 's/IP_EXT/Y.Y.Y.Y/g' -i /etc/default/ngcp-mediaproxy-ng-daemon

* option: use dynamic DNS

# sed -e 's/#SIP_DOMAIN=vm.securecall.org/SIP_DOMAIN=dyndns.whatever.org/' -i /etc/kamailio/kamctlrc

Private environment
-------------------

You can test the VM in your lab without internet access.

* change internal (X.X.X.X) IP:

# sed -e 's/IP_INT/X.X.X.X/g' -i /etc/kamailio/kamailio.cfg
# sed -e 's/IP_INT/X.X.X.X/g' -i /etc/default/ngcp-mediaproxy-ng-daemon

Common
------

* activate daemons:

# sed -e 's/#RUN_KAMAILIO=yes/RUN_KAMAILIO=yes/' -i /etc/default/kamailio
# sed -e 's/RUN_MEDIAPROXY=no/RUN_MEDIAPROXY=yes/ -i /etc/default/ngcp-mediaproxy-ng-daemon

* restart services:

# invoke-rc.d ngcp-mediaproxy-ng-daemon restart
# invoke-rc.d kamailio restart

* add users:

root@securecallvm:/etc/kamailio# kamctl add
ERROR: too few parameters

 -- command 'add|passwd|rm' - manage subscribers

 add <username> <password> .......... add a new subscriber (*)
 show <username> .................... show subscriber attributes (*)
 passwd <username> <passwd> ......... change user's password (*)
 rm <username> ...................... delete a user (*)
