Network Traversal Strategy

Select a profile:

• Application Managed: STUN ON, DNS SRV ON.

Bria will use the STUN server at stun.counterpath.com to discover the public address of your device. It will

present your public address for SIP signaling and both your public and private addresses when negotiating

media routing.

• Server Managed: STUN OFF, DNS SRV ON.

Bria will present your device’s private address for SIP signaling and when negotiating media routing.

Choose this option if your VoIP service provider advises you that it has implemented a network-hosted

NAT traversal (or far-end NAT traversal) technology such as a session border controller (SBC), media

proxy or RTP relay.

• Custom Configuration: Set the settings as desired.

Field Description

DNS SRV • ON: Bria will use DNS SRV to discover the network addresses for your VoIP service

provider's VoIP-related services such as a STUN server, if any.

• OFF: Bria will not use DNS SRV for discovery. Only turn this setting off if your system

administrator advises you to do so.

STUN Server Used only if STUN is ON. The default is stun.counterpath.com. You can specify a different

STUN server if your VoIP provider advises you to do so.

STUN Wi-Fi • ON: Bria will use a STUN server to discover your public IP address.

• OFF: Bria does not discover your public IP address. Therefore, only the private IP address

will be used. Typically, Global IP should be set to OFF.

STUN Mobile This setting has the same function as STUN Wi-Fi, but applies only when you are connected

over the mobile network.
