NethVoice Proxy module is split into two main parts:
- Kamalio: SIP proxy server for managing SIP connections
- RTP Engine: RTP proxy for managing RTP connections
NethVoice Proxy allows you to manage all incoming and outgoing SIP and RTP connections.
The proxy will be used by :ref:`NethVoice <nethvoice-section>` instances that must be installed after this proxy is up and running.
Note
You can install only one NethVoice Proxy per node from the :ref:`software_center-section`.
NethVoice Proxy needs a virtual host, an FQDN like proxy.nethserver.org, this virtual host may be dedicated or shared with the one used in a :ref:`NethVoice <nethvoice-section>` application.
Before proceeding with the configuration, make sure to create the corresponding name record inside your DNS server.
If you are planning to use a Let's Encrypt certificate as default, make also sure to have the corresponding public DNS record.
How to configure:
- access the application configuration page and enter a valid FQDN inside
Proxy Domainfield - insert the network's interface of the node choosing it from the drop-down menu
- insert Public IPv4/IPv6 address that will receive VoIP traffic (necessary only if there is no public IP on the network interface)
Warning
If the machine is not accessible from the internet and its fully qualified domain name (FQDN) cannot be reached externally, and it is used only within a local network, the IP address field should contain the machine's private IP address.
Now, you can install and configure one ore more :ref:`NethVoice <nethvoice-section>` instances.
