How it works
Each Class 4 platform can run multiple softswitch instances. Each of softswitch can connect to the UI via the following section:
Within the VoIP Gateway, you can add your softswitch instance:
Each softswitch has a "name" and this name is configured in the following config:
/opt/denovo/dnl_softswitch/conf/dnl_softswitch.conf
Inside the file, you can see the name :

[general]

switch_name = class4
[CLI]
cli_listen_ip = 127.0.0.1
cli_listen_port = 4320
cli_connection_expires = 600
cli_connection_limit = 200
The CLI interface allow the UI to telnet into the switch and query for switch information.
If started correctly, you should see the following CLI port is up:
tcp 0 0 127.0.0.1:4320 0.0.0.0:* LISTEN 9559/dnl_softswitch
tcp 0 0 127.0.0.1:49292 127.0.0.1:6240 ESTABLISHED 9559/dnl_softswitch
tcp 0 0 127.0.0.1:44122 127.0.0.1:6230 ESTABLISHED 9559/dnl_softswitch
udp 0 0 176.31.100.14:4319 0.0.0.0:* 9559/dnl_softswitch
unix 3 [ ] STREAM CONNECTED 1175410976 9559/dnl_softswitch
unix 2 [ ] DGRAM 1175410045 9559/dnl_softswitch
Once CLI port is up, you can configure the VoIP Gateway as follows:
Now, notice that SIP is not up.
Our next step is to add SIP interface to the VoIP gateway.
After you add a new SIP interface, you can restart softswitch using the following command:
systemctl restart dnl_softswitch
After you restart Class4 softswtich, you can see the SIP interface with 6060 port is started.
