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 IPv4/IPv6 address that will receive VoIP traffic
Now, you can install and configure one ore more :ref:`NethVoice <nethvoice-section>` instances.
