User's Manual 53. Configuration Parameters Reference
Parameter Description
Web/EMS: Gateway
Name
CLI: gw-name
[SIPGatewayName]
Defines a name for the device (e.g., device123.com). This name is used
as the host part of the SIP URI in the From header. If not specified, the
device's IP address is used instead (default).
Notes:

Ensure that the parameter value is the one with which the Proxy has
been configured with to identify the device.

This parameter can also be configured for an IP Group (in the IP
Group table).
[ZeroSDPHandling] Determines the device's response to an incoming SDP that includes an
IP address of 0.0.0.0 in the SDP's Connection Information field (i.e.,
"c=IN IP4 0.0.0.0").

[0] = (Default) Sets the IP address of the outgoing SDP's c= field to
0.0.0.0.

[1] = Sets the IP address of the outgoing SDP c= field to the IP
address of the device. If the incoming SDP doesn’t contain the
"a=inactive" line, the returned SDP contains the "a=recvonly" line.
Web/EMS: Enable
Delayed Offer
[EnableDelayedOffer]
Determines whether the device sends the initial INVITE message with
or without an SDP. Sending the first INVITE without SDP is typically
done by clients for obtaining the far-end's full list of capabilities before
sending their own offer. (An alternative method for obtaining the list of
supported capabilities is by using SIP OPTIONS, which is not supported
by every SIP agent.)

[0] Disable = (Default) The device sends the initial INVITE message
with an SDP.

[1] Enable = The device sends the initial INVITE message without an
SDP.
[DisableCryptoLifeTimeI
nSDP] Enables the device to send "a=crypto" lines without the lifetime
parameter in the SDP. For example, if the SDP contains "a=crypto:12
AES_CM_128_HMAC_SHA1_80
inline:hhQe10yZRcRcpIFPkH5xYY9R1de37ogh9G1MpvNp|2^31", it
removes the lifetime parameter "2^31".

[0] Disable (default)

[1] Enable
Web/EMS: Enable
Contact Restriction
[EnableContactRestricti
on]
Determines whether the device sets the Contact header of outgoing
INVITE requests to ‘anonymous’ for restricted calls.

[0] Disable (default)

[1] Enable
[AnonymousMode]
Determines whether the device's IP address is used as the URI host
part instead of "anonymous.invalid" in the INVITE's From header for
Tel-to-IP calls.

[0] = (Default) If the device receives a call from the Tel with blocked
caller ID, it sends an INVITE with
From: “anonymous”<anonymous@anonymous.invalid>

[1] = The device's IP address is used as the URI host part instead of
"anonymous.invalid".
This parameter may be useful, for example, for service providers who
identify their SIP Trunking customers by their source phone number or
IP address, reflected in the From header of the SIP INVITE. Therefore,
even customers blocking their Caller ID can be identified by the service
provider. Typically, if the device receives a call with blocked Caller ID
