Transport settings (SIP)

Signaling transport: Contact your VoIP service provider to identify the types of transport that are supported.

Automatic: Bria sets up the transport based on the capabilities of the network and the Bria computer. Choose this option if you do not care which transport is used.

TCP (Transmission Control Protocol): This transport provides no signaling security.

UDP (User Datagram Protocol): This transport provides no signaling security.

TLS (Transport Layer Security): Choose this option to request signaling encryption or both signaling and media encryption.

Media Encryption (Windows) / Media Encryption over TLS (Mac): Applies when TLS is chosen as the Signaling transport method (see Signaling transport above).

Make and accept only encrypted call

Outgoing calls: Bria places all outbound calls with TLS. The call INVITE will specify SRTP media encryption. If the correct root certificates are not in place or if the other party does not accept encrypted calls, the call will fail.

Incoming calls: Bria only accepts INVITEs that are for encrypted calls. If Bria receives a call INVITE that is not encrypted, the call will be rejected.

Do not allow encrypted calls

Outgoing calls: Bria only places unencrypted calls. If the other party does not support unencrypted calls, the call will fail.

Incoming calls: Bria only accepts INVITEs that are for unencrypted calls. Bria only accepts INVITEs that are for unencrypted calls.

Verify TLS Certificate: Applies when TLS is chosen for transport.

Selected: Bria attempts to verify one or more of the certificates sent by the SIP server to see if they are trusted. If the certificates are trusted by a well-known certificate authority such as VeriSign, no further action is required. If the certificates are self-signed, install a corresponding CA certificate on your device. Contact your VoIP service provider to get a corresponding CA certificate.

Cleared: Bria accepts the certificate without trying to verify it.

IPv6: Generally, leave this selected. Clear the check box only if advised by your VoIP service provider or your system administrator.

Selected: Allows Bria to make phone calls and send IMs over an IPv6 network.
