SIP Port
Determine on which port the SIP user agent should run. The default port for SIP
is 5060. Leave the default setting unchanged unless you know of any other appli-
cation or protocol that needs this port.
Identity
Anyone who wants to call you directly without using a SIP proxy or a SIP provider
needs to know your valid SIP address. Linphone creates a valid SIP address for
you.
Remote Services
This list holds one or more SIP service providers where you have created a user
account. Server information can be added, modified, or deleted at any time. See
Adding a SIP Proxy and Registering at a Remote SIP Server
about the registration procedure.
Authentication Information
To register at a remote SIP server, provide certain authentication data, such as a
password and username. Linphone stores this data once provided. To discard this
data for security reasons, click Clear all stored authentification data.
The Remote services list can be filled with several addresses of remote SIP proxies or
service providers.
Procedure 8.1 Adding a SIP Proxy and Registering at a Remote SIP Server
1 Choose a suitable SIP provider and create a user account there.
2 Start Linphone.
3 Go to Go → Preferences → SIP.
4 Click Add proxy/registrar to open a registration form.
5 Fill in the appropriate values for Registration Period, SIP Identity, SIP Proxy
and Route. If working from behind a firewall, always select Send registration
and enter an appropriate value for Registration Period. This resends the original
registration data after a given time to keep the firewall open at the ports needed
by Linphone. Otherwise, these ports would automatically be closed if the firewall
did not receive any more packages of this type. Resending the registration data
