received SDP and disregards any subsequently received
18x forking responses (with or without SDP). If the first
response is 180 without SDP, the device responds
according to the PlayRBTone2TEL parameter and
disregards the subsequent forking 18x responses.

[1] Sequential handling = If 18x with SDP is received, the
device opens a voice stream according to the received
SDP. The device re-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 the parameter setting, once a SIP 200
OK response is received, the device uses the RTP information
and re-opens the voice stream, if necessary.
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.
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 Tel-to-IP Routing table.
Defines the interval (in seconds) to wait before sending
INVITE messages to the other members of the forking group.
The INVITE is immediately sent to the first member.
The valid value range is 0 to 40. The default is 0 (i.e., sends
immediately).
