Network Traversal Strategy

Select a profile:

• Application Managed: STUN ON and DNS SRV ON.

Bria will use the specified STUN server to discover the public address of your device. It will present your

public address for SIP signaling. When negotiating media routing, it will present either both your public

and private addresses or just your public address depending on the ICE settings under Account Advanced.

• Server Managed: STUN OFF and 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 but we recommend that you

change this to an address provided by your VoIP service provider. CounterPath cannot

guarantee the availability of their STUN server.

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 to assure that the private IP address is

used for SIP signaling.

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

over the mobile network.
