Field Description
STUN • 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 Server Used only if STUN is ON. The default is counterpath.com. If you select the User
Specified profile you can specify a different STUN server.
ICE ICE is involved only in media routing (it is not involved in SIP signaling).
• ON: 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 iPhone behind a firewall or NAT.
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.
