NAT Traversal (STUN)

 

This parameter defines whether the NAT traversal mechanism is activated. If activated (by

 

 

 

 

 

 

 

choosing “Yes”) and a STUN server is also specified, then the GXV300x will behave ac-

 

 

 

 

cording to the STUN client specification. Using this mode, the embedded STUN client de-

 

 

 

 

tects what type of NAT/Firewall router used and displayed the result in Status Page.

 

 

 

 

If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the

 

 

 

 

GXV300x will attempt to use its mapped public IP address and port in all of its SIP and

 

 

 

 

SDP messages.

 

 

 

 

If the NAT Traversal field is set to “No, but send keep-alive” with no specified STUN server,

 

 

 

 

the GXV300x will periodically (every 20 seconds or so) send a blank UDP packet (with no

 

 

 

 

payload data) to the SIP server to keep the “hole” on the NAT router open.

 

 

 

 

If the detected NAT is symmetric NAT, then STUN can NOT be used and an Outbound

 

 

 

 

Proxy or Session Border Controller must be used and this field must be configured to “NO”.

 

 

 

 

 

 

 

 

 

 

 

 

Keep-Alive Using SIP OP-

 

Default is No

 

 

 

 

 

TIONS

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Subscribe for MWI

 

Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be

 

 

 

 

 

 

 

sent periodically. GXV300x supports both synchronized and non-synchronized MWI.

 

 

 

 

 

 

 

 

 

 

 

 

Proxy-Require

 

 

 

 

 

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

 

 

 

 

Do not configure it unless the server supports this special feature.

 

 

 

 

 

 

 

 

 

 

 

 

SIP Compact Header

 

 

 

 

 

Default is No. If set to Yes, the header is sent in compact format. This is helpful in stateless

 

 

 

 

proxy with multiple codec used as big UDP packet is not router friendly during transit.

 

 

 

 

 

 

 

 

 

 

 

 

Voice Mail User ID

 

 

 

 

 

When configured, user can access VM messages by pressing “MSG” button.

 

 

 

 

This ID is usually the VM portal access number, e.g.: 8500 in Asterisk or 8502 for FWD.

 

 

 

 

 

 

 

 

 

 

 

 

Send DTMF

 

 

 

 

 

This parameter specifies the mechanism to transmit DTMF digit.

 

 

 

 

There are 3 supported modes: in audio which means DTMF is combined in audio signal

 

 

 

 

(not very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP INFO.

 

 

 

 

 

 

 

 

 

 

 

 

Early Dial

 

Default is No. Use only if proxy or server supports 484 response.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Dial Plan Prefix

 

 

 

 

 

Sets the prefix added to each dialed number.
