SIP User's Manual A. Configuration Parameters Reference
Parameter Description
in the Outbound IP Routing table.
Web/EMS: Enable Reason
Header
[EnableReasonHeader]
Enables the usage of the SIP Reason header.
 [0] Disable
 [1] Enable (default)
Web/EMS: Gateway Name
[SIPGatewayName]
Defines a name for the device (e.g., device123.com').
Notes:
 Ensure that the name defined is the one with which the Proxy is
configured to identify the device.
 If specified, the device 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).
[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] = Sets the IP address of the outgoing SDP's c= field to 0.0.0.0
(default).
 [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 = The device sends the initial INVITE message with an
SDP (default).
 [1] Enable = The device sends the initial INVITE message without
an SDP.
[DisableCryptoLifeTimeInS
DP]
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
[EnableContactRestriction]
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
