Network Traversal Strategy

Speak to your VoIP service provider about the strategy to use. Or
leave the default and just change the STUN Server field. Select a
profile to set a specific combination of STUN, ICE, and DNS SRV:

•Mixed Configuration: STUN On, ICE Off, DNS SRV On.

Bria will use the specified STUN server to discover the public address
of your device. It will present that public address for SIP signaling and
when negotiating media routing.

•Application Managed: STUN On, ICE On, 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
and both your public and private addresses when negotiating media
routing.

•Server Managed: STUN Off, ICE 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

STUN Wi-Fi

• On (checked): 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 in this case, Global IP should be turned off.

STUN Mobile

This setting has the same function as STUN, but applies only when you are connected
over mobile network.

ICE Wi-Fi

ICE is involved only in media routing (it is not involved in SIP signaling).

• On (checked): Bria will use ICE to discover addresses for media packets. ICE

provides a good guarantee of two-way audio. However, to use ICE successfully, both
endpoints in a call must use ICE and specifically must use draft 19 of the ICE
standard.

• Off: Try turning ICE off if you are not using Bria behind a firewall or NAT.

ICE Mobile

This setting has the same function as ICE, but applies only when you are connected over
mobile network.

DNS SRV

• On (checked): 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.
