VoIP Provider Settings

Proceed as follows:
• Separately for VoIP providers
• Using the Configuration Manager (page Public switched tel. networks > Voice over IP
(VoIP page) > Provider > Configure)
Note: You can obtain the data for the settings either directly from the VoIP
provider or from suitable lists in the Internet.
Requirements:
• For entering a URL: configured DNS server
• For using a STUN server: IP operating mode IPv4
PROVIDER
Domain
The domain (also known as a "realm", "SIP domain" or "SIP realm") is required for the VoIP
address. The structure of a subscriber's VoIP address is similar to an e-mail address. It is made
up of the VoIP phone number and the domain, separated by the @ character:
<subscriber>@domain.
Registrar
REGISTER requests are sent to the specified registrar (also known as a SIP registrar,
registry, SIP server, SIP registry server). Enter this data as an IP address or a URL.
Notes:
The page Overviews > Ports shows an overview of the PBX ports (incoming
and outgoing).
You should only switch off the registrar if the VoIP provider requires you to do
so. No NAT Keep-Alive is performed if the registrar is disabled. An internal
network is usually protected from external manipulation by, for example, a
firewall integrated in the router. Without NAT Keep-Alive, the firewall's
security functions will defend you against attempted accesses from the
Internet. For this reason, you may need to implement port forwarding for
incoming SIP packets on the SIP port set up in the VoIP provider's configu-
ration.
