Send Internal IP
Some firewall proxies require an internal IP address. The options are Always, Default, and Never.
When set to Always, the IP address of the computer on which the softphone is installed will be sent.
When set to Default, if defined, the outbound proxy’s address will be sent; otherwise, the computer’s
internal address will be sent. When set to Never, the firewall outbound proxy’s address will be sent.
STUN Server
Set this value to enable the ADTRAN IP Softphone to override the STUN host. The STUN protocol is
the preferred protocol for detecting firewall and NAT status.
Firewall Outbound Proxy
Set the DNS name or IP address of the firewall proxy of the user’s local network.
Enable ICE
Check this box to enable ICE. ICE is a protocol that detects the shortest network path during a voice
conversation. This can help overcome certain problems with endpoints behind the same firewall.
Server-side Storage
Figure 6 shows the Server-side Storage menu for a SIP account configuration. Use this menu to indicate
where to store contact information. The information can be stored either locally or remotely using
information provided by the VoIP service provide or administrator. For remote storage, WebDAV or
XCAP protocol must be selected. When the information is complete, select
OK to save the settings.
