GXW450X User Manual
Version 1.0.0.6
The VoIP trunk options are listed in the table below.
Table 28: Create New SIP Trunk
Provider Name
Configure a unique label (up to 64 characters) to identify this trunk when
listed in outbound rules, inbound rules and etc.
Host Name
Configure the IP address or URL for the VoIP provider’s server of the
trunk.
NAT
Turn on this setting when the gateway
is using public IP and
communicating with devices behind NAT. If there is one-way audio issue,
usually it is related to NAT configuration or SIP/RTP port support on the
firewall.
Disable This Trunk
If checked, the trunk will be disabled.
Note: If a current SIP trunk is disabled, GXW450X
will send
UNREGISTER message (REGISTER message with expires=0) to the
SIP provider.
TEL URI
If the trunk has an assigned PSTN telephone number, this field should be
set to "User=Phone". Then a "User=Phone" parameter will be attached to
the Request-Line and TO header in the SIP request to indicate the E.164
number. If set to "Enable", "Tel:" will be used instead of "SIP:" in the SIP
request. The default setting is disabled.
Caller ID
Configure the Caller ID. This is the number that the trunk will try to use
when making outbound calls. For some providers, it might not be
possible to set the CallerID with this option and this option will be
ignored.
Important Note: When making outgoing calls, the following priority order
rule will be used to determine which CallerID will be set before sending
out the call:
From user (Register Trunk Only)  CID from inbound call (Keep
Original CID Enabled)  Trunk Username/CallerID (Keep Trunk CID
Enabled)  DOD Trunk Username/CallerID (Keep Trunk CID
Disabled)  Global Outbound CID.
CallerID Name
Configure the name of the caller.
From Domain
Configure the actual domain name. This can be used to override the
