Configuration
To configure incoming call authorization with SMG gateway, specify SMG gateway configuration file in call.gate.outgoing.call.config parameter of /etc/eltex-ngw/notification.properties configuration file.
Example:
#Call gate configuration call.gate.outgoing.call.config=smg_gate.conf call.gate.pool.size=50 pool.wait.millis=5000
Configure SMG gateway interaction in smg_gate.conf configuration file (it is located in the same directory as notification.properties).
smg.host=<ip-address> smg.port=3799 smg.secret=radiuspass listen.port=1814 listen.secret=radiuspass1
smg.host = SMG gateway addresssmg.port = the port that listens to SMG
gatewaysmg.secret = RADIUS-Authorization key configured on SMG gateway
listen.port = the port that listens to NGW. Any relevant port can be configured; it is required to specify a new port on SMG gateway
listen.secret = RADIUS Accounting key
After configuration files are modified, restart eltex-ngw server
root@vagrant-ubuntu16-xenial-64-SWLC:~# service eltex-ngw restart
Check
To check SMG gateway connection, use radclient utility and make a CoA request containing a telephone number to which an incoming call should come in.
root@vagrant-ubuntu16-xenial-64-SWLC:~# echo Called-Station-Id="79964567890" | radclient -sx 192.168.1.10:3799 coa radiuspass
Sending CoA-Request of id 150 to 192.168.1.10 port 3799
Called-Station-Id = "79964567890"
rad_recv: CoA-ACK packet from host 192.168.1.10 port 3799, id=150, length=33
Calling-Station-Id = "73830012345"
Total approved auths: 1
Total denied auths: 0
Total lost auths: 0
CoA-ACK with Calling-Station-id containing a telephone number from which a call will be made, should be received in response.
