These fields are optional and provided to store the administrator’s name, phone
number, and email address so that they can be contacted for any issue requiring
attention. You may also enter a name in the System Name field to identify your
GXE502X.
o SIP Static Mapped IP and port Configuration:
The SIP port for the GXE502X can be set to either the default of 5060 in the SIP Port
field, or another port number may be used. The SIP Static Mapped WAN IP and the
SIP Static Mapped WAN Port for Udp may also be changed in the respective fields.
o SIP Static Mapped WAN Port for CBCom
This Value is reserved for China’s CBCOM SIP trunk provider.
o Start of UDP Port for Media Transfer
When this value is set, the GXE502X will use the value within “value+2000” for the local
UDP port for its media,this is useful when the GXE502X is behind a NAT and the NAT is
configured to do port forwarding with “value+2000” for UDP ports.
o STUN Server ( for NAT traversal):
If the GXE502X is behind a non-symmetric NAT router, it may be necessary to use
STUN to allow GXE502X to reliably communicate via IP through the router. Enter a
STUN server IP address or domain name in the STUN Server field.
o Voicemail-to-Email Configuration::
To configure the GXE502X to send out voicemail via email, the related SMTP setting
must be configured. The receiving email address can be configured in the Extensions
Directory sub menu of Phone Extensions configuration.
There are two ways to configure the GXE502X to send emails:
1) Configure as email client. This requires an SMTP server to forward all outgoing
emails via that particular authorized email client account.
Configure as MTA. This usually must be handled by the system administrator. This will
analyze the destination email address and resolve it using the domain name of the destination
email server.
