BASIC/ZERO CONFIG
By default, zero config feature is turned on in GXE5102/5104/5108/5116 so the devices connected in the
same LAN will be auto provisioned by the GXE. There are three methods of auto provision: SIP subscribe,
DHCP option 66 and mDNS. Basically, when the device boots up, it will send the SUBSCRIBE to LAN. The
GXE will find it, create and assign an extension to the device, and then return the url of config file for the
device to download.
Here is the Auto Provision Setting:

default port number is 5061 if not specified.
Note:
The IP address must match the common name (hostname) in the
certificate. Please do not bind a TLS socket to multiple IP addresses.
For details on how to construct a certificate for SIP, please refer to the
following document:
http://tools.ietf.org/html/draft-ietf-sip-domain-certs
TLS Self Signed CA This is the CA certificate is the TLS server being connected to requires
self signed certificate, including server's public key. This file will be
renamed as "asterisk.ca" automatically.
Note:
The size of your ca file can't be larger than 2MB.
TLS Cert This is the Certificate file (*.pem format only) used for TLS connections.
This file will be renamed as "asterisk.pem" automatically.
Note:
The size of your certificate can't be larger than 2MB.
TLS CA Cert This file must be named with the CA subject name hash value. It
contains CA's (Certificate Authority) public key, which is used to verify
the accessed servers.
Note:
The size of your certificate can't be larger than 2MB.
TLS CA List The list of files under the CA Cert directory.
SIP SETTINGS/SIP NAT
External Address A static address (and port) that will be in outbound SIP messages if the
GXE is behind NAT. If it's a hostname, it will only be looked up only.

the hostname will be looked up every "External Refresh" interval and
Asterisk will perform DNS queries periodically.
External Refresh Configures the refresh interval for the external host.
External TCP Port Configures the externally mapped TCP port when the GXE
is behind a
Firmware version 1.0.0.19 GXE5102/5104/5108/5116 USER MANUAL Page 41 of 52
static NAT or PAT.
External TLS Port Configures the externally mapped TLS port when GXE is behind a static
NAT or PAT. The default value is 5061.
Local Network Address A list of network addresses that are considered inside
of the NAT
network. Multiple entries are allowed, e.g., a reasonable set could be as
follows:
192.168.0.0/255.255.0.0
NAT Mode This is a global NAT setting that will affects all peers and users.
• No: Use rport if the remote side requires it.
• Force rport: Force rport to always be on. This is the default setting.
•
Yes: Force rport to always be on and perform comedia RTP
handling.
• Comedia: Use rport if the remote side requires it
and perform
comedia RTP handling.
Note:
"comedia RTP handling" refers to the technique of sending RTP to the
port where the other endpoint's RTP comes from. This can also be
rephrased as "connection-oriented media".
Allow RTP Reinvite When turned on, the GXE will try to redirect the RTP media stream
(audio) to go directly from the caller to the callee.
• Yes: Enables RTP Reinvite.
• NoNAT: Allows media path redirection (reinvite) but only when the
peer is not be behind NAT. The RTP core can determine if the peer
is behind NAT or not based on the IP address where the media
comes from.
• Update: use UPDATE for media path redirection, instead of INVITE.
Note:
Some devices do not support this (especially if one of them is behind
NAT).
