Version 6.6 569 Mediant 2000
User's Manual 45. Configuration Parameters Reference
Parameter Description
opens the stream according to subsequently received 18x responses
with SDP, or plays a ringback tone if 180 response without SDP is
received. If the first received response is 180 without SDP, the
device responds according to the PlayRBTone2TEL parameter and
processes the subsequent 18x forking responses.
Note: Regardless of this parameter setting, once a SIP 200 OK
response is received, the device uses the RTP information and re-
opens the voice stream, if necessary.
Web: Forking Timeout
[ForkingTimeOut]
Defines the timeout (in seconds) that is started after the first SIP 2xx
response has been received for a User Agent when a Proxy server
performs call forking (Proxy server forwards the INVITE to multiple SIP
User Agents). The device sends a SIP ACK and BYE in response to
any additional SIP 2xx received from the Proxy within this timeout. Once
this timeout elapses, the device ignores any subsequent SIP 2xx.
The number of supported forking calls per channel is 20. In other words,
for an INVITE message, the device can receive up to 20 forking
responses from the Proxy server.
The valid range is 0 to 30. The default is 30.
Web: Tel2IP Call Forking
Mode
[Tel2IPCallForkingMode
]
Enables Tel-to-IP call forking, whereby a Tel call can be routed to
multiple IP destinations.
 [0] Disable (default)
 [1] Enable
Note: Once enabled, routing rules must be assigned Forking Groups 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
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
